Verse 15. - And they went in unto Noah into the ark (cf. Genesis 6:20, which affirmed they should come), two and two of all flesh, wherein is the breath of life. Cf. the three expressions for an animated creature - חַיָּה (Genesis 1:30), יְקוּס: (Genesis 7:4), אֲשֶׂראּבּו רוּחַ חיִּיס.

7:13-16 The ravenous creatures were made mild and manageable; yet, when this occasion was over, they were of the same kind as before; for the ark did not alter their natures. Hypocrites in the church, who outwardly conform to the laws of that ark, are yet unchanged; and it will appear, one time or other, what kind they are after. God continued his care of Noah. God shut the door, to secure him and keep him safe in the ark; also to keep all others for ever out. In what manner this was done, God has not been pleased to make known. There is much of our gospel duty and privilege to be seen in Noah's safety in the ark. The apostle makes it a type of christian baptism, 1Pe 3:20,21. Observe then, it is our great duty, in obedience to the gospel call, by a lively faith in Christ, to come into that way of salvation which God has provided for poor sinners. Those that come into the ark, should bring as many as they can with them, by good instructions, by persuasions, and by good examples. There is room enough in Christ for all comers. God put Adam into paradise, but did not shut him in, so he threw himself out; but when God put Noah into the ark, and so when he brings a soul to Christ, the salvation is sure: it is not in our own keeping, but in the Mediator's hand. But the door of mercy will shortly be shut against those that now make light of it. Knock now, and it shall be opened, Lu 13:25.And they went in unto Noah into the ark,.... Noah went in first, and the creatures of themselves came to him, or were conducted by the ministry of angels; and they were delivered into his hands, and he placed them in the ark as was most convenient for them: it is very likely he went in and out as occasion required, for the better management and disposition of things; for he seems to be the last of all that went in, see Genesis 7:16,

two and two of all flesh, wherein is the breath of life; they that went by sevens, yet being seven couples, as has been observed, as those which were only two or four, went by pairs: this is true of them all.
