Deuteronomy 21:17

But he shall acknowledge the first-born of the hated one to give to him double of all things which shall be found by him, because he is the first of his children, and to him belongs the birthright.

But he shall acknowledge the firstborn of the hated one to give to him double of all things which shall be found by him, because he is the first of his children, and to him belongs the birthright.

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.
