Psalm CXXXVII.5690    Lat. CXXXVI. A sermon to the people

1. …But to-day we have sung, “By the waters of Babylon we sat down and wept, when we remembered Sion” (ver. 1).…

2. Observe “the waters of Babylon.” “The waters of Babylon” are all things which here are loved, and pass away. One man, for example, loveth to practise husbandry, to grow rich thereby, to employ his mind therein, thence to gain pleasure: let him observe the issue, and see that what he hath loved is not a foundation of Jerusalem, but a stream of Babylon. Another saith, It is a grand thing to be a soldier: all husbandmen fear those who are soldiers.…

3. But then other citizens of the holy Jerusalem, understanding their captivity, mark how the natural wishes and the various lusts of men hurry and drag them hither and thither, and drive them into the sea; they see this, and they throw not themselves into the waters of Babylon, but “sit down and weep,” either for those who are being carried away by them, or themselves whose deserts have placed them in Babylon, but sitting, that is, humbling themselves. O holy Sion, where all stands firm and nothing flows! Who hath thrown us headlong into this? Why have we left thy Founder and thy society? Behold, placed where all things are flowing and gliding away, scarce one, if he can grasp the tree, shall be snatched from the stream and escape. Humbling ourselves then in our captivity, let us “sit by the waters of Babylon,” let us not dare to plunge ourselves in those streams, nor to be proud and lifted up in the evil and sadness of our captivity, but let us sit, and so weep. Let us sit “by” the waters, not beneath the waters, of Babylon; such be our humility, that it overwhelm us not. Sit “by” the waters, not “in” the waters, not “under” the waters; but yet sit, in humble fashion, talk not as thou wouldest in Jerusalem.…

4. For many weep with the weeping of Babylon, because they rejoice also with the joy of Babylon. When men rejoice at gains and weep at losses, both are of Babylon. Thou oughtest to weep, but in the remembrance of Sion. If thou weepest in the remembrance of Sion, thou oughtest to weep even when it is well with thee in Babylon.…

5. “On the willows in the midst thereof we hung up our instruments of music” (ver. 2). The citizens of Jerusalem have their “instruments of music,” God’s Scriptures, God’s commands, God’s promises, meditation on the life to come; but while they are dwelling “in Babylon,” they “hang up their instruments.” Willows are unfruitful trees, and here so placed, that no good whatever can be understood of them: elsewhere perhaps there may. Here understand barren trees, growing by the waters of Babylon. These trees are watered by the waters of Babylon, and bring forth no fruit; just as there are men greedy, covetous, barren in good works, citizens of Babylon in such wise, that they are even trees of that region; they are fed there by these pleasures of transitory things, as though watered by “the waters of Babylon.” Thou seekest fruit of them, and nowhere findest it.…Therefore by deferring to apply the Scriptures to them, “we hang up our instruments of music upon the willows.” For we hold them not worthy to carry our instruments. We do not therefore insert our instruments into them and bind them to them, but defer to use them, and so hang them up. For the willows are the unfruitful trees of Babylon, fed by temporal pleasures, as by the “waters of Babylon.”

6. “For there they that led us captive demanded of us words of songs, and they that led us away, an hymn” (ver. 3). They demanded of us words of songs and an hymn, who led us captive.…We are tempted by the delights of earthly things, and we struggle daily with the suggestions of unlawful pleasures; scarce do we breathe freely even in prayer: we understand that we are captives. But who led us captive? what men? what race? what king? If we are redeemed, we once were captives. Who hath redeemed us? Christ. From whom hath He redeemed us? From the devil. The devil then and his angels led us captive: and they would not lead us, unless we consented.…

7. “Those” then “who have led us captive,” the devil and his angels, when have they spoken unto us: “Sing us one of the songs of Sion”? What answer we? Babylon beareth thee, Babylon containeth thee, Babylon nourisheth thee, Babylon speaks by thy mouth, thou knowest not to take in save what glitters for the present, thou knowest not how to meditate on things of eternity, thou takest not in what thou askest. “How shall we sing the Lord’s song in a strange land?” (ver. 4). Truly, brethren, so it is. Begin to wish to preach the truth in such measure as ye know it, and see how needful it is for you to endure such mockers, persecutors of the truth, full of falsehood. Reply to them, when they ask of you what they cannot take in, and say in full confidence of your holy song, “How shall we sing the Lord’s song in a strange land!”

8. But take heed how thou dwellest among them, O people of God, O body of Christ, O high-born band of wanderers (for thy home is not here, but elsewhere), lest when thou lovest them, strivest for their friendship, and fearest to displease such men, Babylon begin to delight thee and thou forget Jerusalem. In fear then of this, see what the Psalmist subjoins, see what follows. “If I forget thee, O Jerusalem” (ver. 5), amid the speeches of those who hold me captive, amid the speeches of treacherous men, amid the speeches of men who ask with ill intent, asking, yet unwilling to learn.…What then? “If I forget thee, O Jerusalem, let my right hand forget me.”

9. “Let my tongue cleave to my jaws, if I remember not thee” (ver. 6). That is, let me be dumb, he saith, if I remember not thee. For what word, what sound doth he utter, who uttereth not songs of Sion? That is our tongue, the song of Jerusalem. The song of the love of this world is a strange tongue, a barbarous tongue, which we have learnt in our captivity. Dumb then will he be to God, who forgetteth Jerusalem. And it is not enough to remember: for her enemies too remember her, desiring to overthrow her. “What is that city?” say they; “who are the Christians? what sort of men are the Christians? would they were not Christians.” Now the captive band hath conquered its capturers; still they murmur, and rage, and desire to slay the holy city that dwells as a stranger among them. Not enough then is it to remember: take heed how thou rememberest. For some things we remember in hate, some in love. And so, when he had said, “If I forget thee, O Jerusalem,” etc., he added at once, “if I prefer not Jerusalem in the height of my joy.” For there is the height of joy where we enjoy God, where we are safe of united brotherhood, and the union of citizenship. There no tempter shall assail us, no one be able so much as to urge us on to any allurement: there nought will delight us but good: there all want will die, there perfect bliss will dawn on us.

10. Then he turneth to God in prayer against the enemies of that city. “Remember, O Lord, the children of Edom” (ver. 7). Edom is the same who is also called Esau: for ye heard just now the words of the Apostle read, “Jacob have I loved, but Esau have I hated.”5691    Rom. ix. 13.…Esau then signifieth all the carnal, Jacob all the spiritual.…All carnal persons are enemies to spiritual persons, for all such, desiring present things, persecute those whom they see to long for things eternal. Against these the Psalmist, looking back to Jerusalem, and beseeching God that he may be delivered from captivity, saith—what? “Remember, O Lord, the children of Edom.” Deliver us from carnal men, from those who imitate Esau, who are elder brethren, yet enemies. They were first-born, but the last-born have won the pre-eminence, for the lust of the flesh hath cast down the former, the contempt of lust hath lifted up the latter. The other live, and envy, and persecute. “In the day of Jerusalem.” The day of Jerusalem, wherein it was tried, wherein it was held captive, or the day of Jerusalem’s happiness, wherein it is freed, wherein it reaches its goal, wherein it is made partaker of eternity? “Remember,” saith he, “O Lord,” forget not those “who said, Rase it, rase it, even to the foundation thereof.” Remember then, it means, that day wherein they willed to overthrow Jerusalem. For how great persecutions hath the Church suffered! How did the children of Edom, that is, carnal men, servants of the devil and his angels, who worshipped stocks and stones, and followed the lusts of the flesh, how did they say, “Extirpate the Christians, destroy the Christians, let not one remain, overthrow them even to the foundation!” Have not these things been said? And when they were said, the persecutors were rejected, the martyrs crowned.…

11. Then he turneth himself to her, “O daughter of Babylon, unhappy;” unhappy in thy very exulting, thy presumption, thine enmity; “unhappy daughter of Babylon!” (ver. 8). The city is called both Babylon, and daughter of Babylon: just as they speak of “Jerusalem” and “the daughter of Jerusalem,” “Sion” and “the daughter of Sion,” “the Church” and “the daughter of the Church.” As it succeedeth the other, it is called “daughter;” as it is preferred before the other, it is called “mother.” There was a former Babylon; did the people
