Genesis 38:28-29

28And so it was, when she was giving birth, that the one put out his hand; and the midwife took a scarlet thread and bound it on his hand, saying, “This one came out first.”

29Then it happened, as he drew back his hand, that his brother came out unexpectedly; and she said, “How did you break through? This breach be upon you!” Therefore his name was called Perez.
