Genesis 4:1 ASV

¹  And the man knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man with `the help of' Jehovah.

²  And again she bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.

³  And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto Jehovah.
