Deuteronomy 21:17

English Standard Version

17 but he shall acknowledge the firstborn, the son of the unloved, by giving him a double portion of all that he has, for he is the firstfruits of his strength. The right of the firstborn is his. (Ge 25:31; Ge 25:33; Ge 27:36; Ge 49:3) 

New International Version

17 He must acknowledge the son of his unloved wife as the firstborn by giving him a double share of all he has. That son is the first sign of his father’s strength. The right of the firstborn belongs to him. 

New International Reader’s Version

17 He must recognise the full rights of the eldest son. He must do it, even though that son is the son of the wife he doesn’t love. He must give that son a double share of everything he has. That son is the first sign of his father’s strength. So the rights of the eldest son belong to him. 

King James Version

17 But he shall acknowledge the son of the hated for the firstborn, by giving him a double portion of all that he hath: for he is the beginning of his strength; the right of the firstborn is his.
