Verse 3 (Genesis 6:3)

And the Lord said ,.... Not to Noah, as in Genesis 6:13 for, as yet, he is not taken notice of, or any discourse addressed to him; but rather to or within himself, he said what follows, or thus concluded, and resolved on in his own mind:

my Spirit shall not always strive with man ; meaning either the soul of man, called the Spirit of God, Job 27:3 because of his creation, and is what he breathes and puts into men, and therefore is styled the Father of spirits; and which is in man, as some in Aben Ezra observe to be the sense the word used, as a sword in the scabbard; and so the meaning is, it shall not always abide there, but be unsheathed and drawn out; man shall not live always, since he is corrupt, and given to carnal lusts: or else, as Jarchi thinks, God himself is meant, and that the sense is, my Spirit shall not always contend within myself; or there shall not always be contention within me concerning man, whether I shall destroy him, or have mercy on him; I am at a point to punish him, since he is wholly carnal: or rather this is to be understood of the Holy Spirit of God, as the Targum of Jonathan, which agrees with 1 Peter 3:18 and to be thus interpreted; that the Spirit of God, which had been litigating and reasoning the point, as men do in a court of judicature, as the word signifies, with these men in the court, and at the bar of their own consciences, by one providence or by one minister or another, particularly by Noah, a preacher of righteousness, in vain, and to no purpose; therefore, he determines to proceed no longer in this way, but pass and execute the sentence of condemnation on them:

for that he also is flesh ; not only carnal and corrupt, but sadly corrupted, and wholly given up to and immersed in sensual lusts and carnal pleasures, so as not to be restrained nor reformed; even the posterity of Seth, professors of religion also, as well as the profane world and posterity of Cain:

yet his days shall be an hundred and twenty years : meaning not the term of man's life, reduced to this from the length of time he lived before the flood; but this designs the space that God would give for repentance, before he proceeded to execute his vengeance on him; this is that "longsuffering of God" the apostle speaks of in the afore mentioned place, "that waited in the days of Noah, while the ark was preparing"; and so both the Targums of Onkelos and Jonathan interpret it of a space of an hundred and twenty years given them to repent: now whereas it was but an hundred years from the birth of Japheth to the flood, some think the space was shortened twenty years, because of their impenitence; but it is more probable what Jarchi observes, that this decree was made and given out twenty years before his birth, though here related, by a figure called "hysteron proteron", frequent in the Scriptures.
