(15-19) Go forth . . . --At the end of exactly a solar year, thus curiously rectified, Noah, his family, and all the animals belonging to the Noachian world-circle are to leave the ark. The vast extent of the flood, and the total destruction of all that had existed before, is indicated by the repetition of the primaeval command, in Genesis 1:22, "to be fruitful and multiply upon the earth." Whatever the flood may have been with respect to the whole globe, it was to Noah and his race absolutely a. new beginning of things.
Verses 15-17. - And God spake unto Noah, saying, Go forth of the ark. For which command doubtless the patriarch waited, as he had done for instructions to enter in (Genesis 7:11), "being restrained by a hallowed modesty from allowing himself to enjoy the bounty of nature till he should hear the voice of God directing him to do so" (Calvin). Thou, and thy wife, and thy sons, and thy sons' wives with thee. The order is different, in Genesis 7:7, whence Ambrose noteth, "non commiscetur sexus in introitu, sod commiscetur in ingressu." Bring forth with thee - God having preserved alive the creatures that a twelvemonth before had been taken into the ark, and were now to be restored to their appropriate habitations on the earth - every living thing that is with thee, of all flesh, both of fowl, and of cattle, and of every creeping thing that creepeth upon the earth (cf. Genesis 7:21; Genesis 9:10); that they may breed abundantly- sharatz, to creep or crawl, used of reptiles and small water animals (Genesis 1:20; Genesis 7:21); hence to swarm, or multiply (Genesis 9:7) - in the earth, and be fruitful (Genesis 1:22), and multiply - literally, become numerous - upon the earth.
8:13-19 God consults our benefit, rather than our desires; he knows what is good for us better than we do for ourselves, and how long it is fit our restraints should continue, and desired mercies should be delayed. We would go out of the ark before the ground is dried; and perhaps, if the door, is shut, are ready to thrust off the covering, and to climb up some other way; but God's time of showing mercy is the best time. As Noah had a command to go into the ark, so, how tedious soever his confinement there was, he would wait for a command to go out of it again. We must in all our ways acknowledge God, and set him before us in all our removals. Those only go under God's protection, who follow God's direction, and submit to him.
And God spake unto Noah, saying,.... Whether in a dream or vision, or by an articulate voice, appearing in an human form, or by an impulse on his mind, is not certain; however, the Lord spoke so to him, that he heard him and understood him: it was, no doubt, very rejoicing to him, since he had not heard his voice for a year or more, at least that we read of; and what he said to him was as follows.
