And when she was in labor, one baby put out his hand; and the midwife took his hand and bound upon it a scarlet thread, saying, This baby was born first.
Afterward his brother came forth, and his hand grasped Esau's heel; so he was named Jacob [supplanter]. Isaac was sixty years old when she gave birth to them.
But he drew back his hand, and behold, his brother was born first. And she said, What a breaking forth you have made for yourself! Therefore his name was called Perez [breaking forth]. [Matt. 1:3.]
