20. Adah gave birth to Jabal. He was the father of those who live in tents and raise livestock.
21. His brother's name was Jubal. He was the father of everyone who plays the harp and flute.

24. Anyone who would have killed Cain would have been paid back seven times. But anyone who hurts me will be paid back 77 times."
25. Adam made love to his wife again. She gave birth to a son and named him Seth. She said, "God has given me another child. The child will take the place of Abel, because Cain killed him."
