And Adam again had relations with his wife, and she gave birth to a son and named him Seth, saying, “God has granted me another seed in place of Abel, since Cain killed him.”
25. Adam knew his wife again . Some hence infer that our first parents were entirely deprived of their offspring when one of their sons had been slain, and the other was cast far away into banishment. But it is utterly incredible that, when the benediction of God in the propagation of mankind was in its greatest force, Adam and Eve should have been through so many years unfruitful.
This is the first mention of Adam in the story of this chapter. No question, the murder of Abel, and the impenitence and apostasy of Cain, were a very great grief to him and Eve, and the more because their own wickedness did now correct them and their backslidings did reprove them.
Commenting on Genesis 4:25-26
God - hath appointed me another seed instead of Abel - Eve must have received on this occasion some Divine communication, else how could she have known that this son was appointed in the place of Abel, to continue that holy line by which the Messiah was to come?
