I. (1) "And God cast out Adam, and placed him opposite the paradise of happiness; and he placed there the cherubim and a flaming sword, which turned every way, to keep the way of the tree of Life.[Ge 3:24.] In this place Moses uses the expression, "He cast out," but previously he said, "He sent out," not using the various expressions at random, but being well aware with reference to what parts he was employing them with propriety and felicity. (2) Now a man who is sent out is not hindered from returning at some subsequent time; but he who is cast out by God must endure an eternal banishment, for it is granted to him who has not yet been completely and violently taken prisoner by wickedness, to repent, and so to return back to virtue, from which he has been driven, as to his great country; but he who is weighed down by, and wholly subjected to, a violent and incurable disease, must bear his misfortunes for ever, being for all times unalterably cast out into the place of the wicked, that there he may endure unmitigated and everlasting misery. [Ge 16:9.] (3) Since we see Agar, [Ge 21:14.] by whom we understand the middle kind of instruction which is confined to the encyclical system, twice going forth from Sarah, who is the symbol of predominant virtue, and once returning back by the same road, inasmuch as after she had fled the first time, without being banished by her mistress, she returned to see her master's house, having been met by an angel, as the holy scriptures read: but the second time, she is utterly cast out, and is never to be brought back again.
