Vs. 8-9. And he sent forth a dove from him, to see if the waters were abated from off the face of the ground; but the dove found no rest for the sole of her foot, and she returned unto him to the ark; for the waters were on the face of the whole earth: and he put forth his hand, and took her, and brought her unto him into the ark.
25. When Noah's hopes had been set at naught by the raven, which flew about wantonly but brought no tidings concerning the condition of the earth, he took a dove, thinking that she would more truly perform the mission. The text almost authorizes us to say that those two birds were sent forth at the same time, so that Noah might have two witnesses from whom to gain desired knowledge. The raven enjoying the free sky, flew round about the ark, but did not want to return into it. The dove, however, fleeing from the corpses and corruption, comes back and permits itself to be caught. This story, as we shall hear, offers a fine allegory concerning the Church.
Vs. 10-12. And he stayed yet other seven days; and again he sent forth the dove out of the ark; and the dove came in to him at eventide; and, lo, in her mouth an olive-leaf plucked off: so Noah knew that the waters were abated from off the earth. And he stayed yet other seven days, and sent forth the dove; and she returned not again unto him any more.
26. The dove, being a faithful messenger, is sent forth once more. Moses carefully describes how the waters decreased gradually, until at last the surface of the earth, together with the trees, was laid bare. We do not believe that the dove brought the olive leaf intentionally, but by the command of God, who wanted to show Noah, little by little, that he had not altogether forgotten but remembered him. This olive leaf was an impressive sign to Noah and his fellow-prisoners in the ark, bringing them courage and hope of impending liberation.
27. The Jews dispute sharply in respect to this matter of where the dove found the olive leaf, and some, in order to secure special glory for their homeland, make the ludicrous assertion that she took it from the Mount of Olives in the land of Israel, which God had spared from the flood that destroyed the remainder of the earth. But the saner Jews rightly refute this nonsense by arguing that if this were true, the olive leaf could not have been a sign for Noah that the waters had fallen. Others have invented the fable that the dove was admitted to paradise and brought the leaf from there.
28. But I have (ch 2, §39-42) set forth at length my views concerning paradise, and this nonsense is not worthy the effort of a refutation. It serves a better purpose to remind you that all these things happened miraculously and supernaturally. A dove is not so intelligent as to pluck a bough and bring it to the ark in order that Noah might form a judgment with reference to the decrease of waters. God ordained these events. Other trees had leaves at that time, particularly the taller ones which rose sooner from the waters. The olive tree is comparatively short, hence it was calculated to furnish information concerning the decrease of the waters and to serve as an object lesson of the cessation of the wrath of God and the return of the earth to its former state. Of this he had more certain proof however, when the dove, having been sent out the third time, did not return: for not only did it find food on earth, but was able to build nests and to flit to and fro.
