Genesis 4:1-3

Amplified Bible, Classic Edition

4 And Adam knew Eve as his wife, and she became pregnant and bore Cain; and she said, I have gotten and gained a man with the help of the Lord.

² And [next] she gave birth to his brother Abel. Now Abel was a keeper of sheep, but Cain was a tiller of the ground.

³ And in the course of time Cain brought to the Lord an offering of the fruit of the ground.
