Genesis 4:3 WEB

¹  The man knew Eve his wife. She conceived, and gave birth to Cain, and said, 'I have gotten a man with Yahweh's help.'

²  Again she gave birth, to Cain's brother Abel. Abel was a keeper of sheep, but Cain was a tiller of the ground.

³  As time passed, it happened that Cain brought an offering to Yahweh from the fruit of the ground.

⁴  Abel also brought some of the firstborn of his flock and of the fat of it. Yahweh respected Abel and his offering,

⁵  but he didn't respect Cain and his offering. Cain was very angry, and the expression on his face fell.
