‏ Genesis 6:5

Gen 6:5-8

Now when the wickedness of man became great, and “every imagination of the thoughts of his heart was only evil the whole day,” i.e., continually and altogether evil, it repented God that He had made man, and He determined to destroy them. This determination and the motive assigned are also irreconcilable with the angel-theory. “Had the godless race, which God destroyed by the flood, sprung either entirely or in part from the marriage of angels to the daughters of men, it would no longer have been the race first created by God in Adam, but a grotesque product of the Adamitic factor created by God, and an entirely foreign and angelic factor” (Phil.).
When, on the other hand, the supporters of the angel marriages maintain that it is only on this interpretation that the necessity for the flood, i.e., for the complete destruction of the whole human race with the exception of righteous Noah, can be understood, not only is there no scriptural foundation for this argument, but it is decidedly at variance with those statements of the Scriptures, which speak of the corruption of the men whom God had created, and not of a race that had arisen through an unnatural connection of angels and men and forced their way into God’s creation. If it were really the case, that it would otherwise be impossible to understand where the necessity could lie, for all the rest of the human race to be destroyed and a new beginning to be made, whereas afterwards, when Abraham was chosen, the rest of the human race was not only spared, but preserved for subsequent participation in the blessings of salvation: we should only need to call Job to mind, who also could not comprehend the necessity for the fearful sufferings which overwhelmed him, and was unable to discover the justice of God, but who was afterwards taught a better lesson by God Himself, and reproved for his rash conclusions, as a sufficient proof of the deceptive and futile character of all such human reasoning.) But this is not the true state of the case. The Scriptures expressly affirm, that after the flood the moral corruption of man was the same as before the flood; for they describe it in Gen 8:21 in the very same words as in Gen 6:5 : and the reason they assign for the same judgment not being repeated, is simply the promise that God would no more smite and destroy all living, as He had done before-an evident proof that God expected no change in human nature, and out of pure mercy and long-suffering would never send a second flood. “Now, if the race destroyed had been one that sprang from angel-fathers, it is difficult to understand why no improvement was to be looked for after the flood; for the repetition of any such unnatural angel-tragedy was certainly not probable, and still less inevitable” (Philippi).

The force of ינּחם, “it repented the Lord,” may be gathered from the explanatory יתעצּב, “it grieved Him at His heart.” This shows that the repentance of God does not presuppose any variableness in His nature of His purposes. In this sense God never repents of anything (1Sa 15:29), “quia nihil illi inopinatum vel non praevisum accidit” (Calvin). The repentance of God is an anthropomorphic expression for the pain of the divine love at the sin of man, and signifies that “God is hurt no less by the atrocious sins of men than if they pierced His heart with mortal anguish” (Calvin). The destruction of all, “from man unto beast,” etc., is to be explained on the ground of the sovereignty of man upon the earth, the irrational creatures being created for him, and therefore involved in his fall. This destruction, however, was not to bring the human race to an end. “Noah found grace in the eyes of the Lord.” In these words mercy is seen in the midst of wrath, pledging the preservation and restoration of humanity.

Gen 6:9-12 contain a description of Noah and his contemporaries; Gen 6:13-22, the announcement of the purpose of God with reference to the flood.
