²⁷ The time came for Tamar to give birth, and there were twins! ²⁸ While she was giving birth, one baby put out his hand. The woman who was helping Tamar tied a red string to that baby's arm. She said, ‘This baby came out first.’ ²⁹ But then the baby moved his hand back inside and his brother came out first. The woman said, ‘You have opened a way for yourself to come out!’ So they gave him the name ‘Perez’.^[a]
