Ge 4:1-26. Birth of Cain and Abel.
1. Eve said, I have gotten a man from the Lord—that is, "by the help of the Lord"—an expression of pious gratitude—and she called him Cain, that is, "a possession," as if valued above everything else; while the arrival of another son reminding Eve of the misery she had entailed on her offspring, led to the name Abel, that is, either weakness, vanity (Ps 39:5), or grief, lamentation. Cain and Abel were probably twins; and it is thought that, at this early period, children were born in pairs (Ge 5:4) [Calvin].
