Deuteronomy 21:15-17

Revised Geneva Translation

¹⁵ “If a man has two wives—one loved and another hated—and they have born him children (both the loved and also the hated), if the firstborn is the son of the hated,

¹⁶ “then, when the time comes that he appoints his sons to be heirs of that which he has, he may not make the son of the beloved firstborn before the son of the hated, who is the firstborn.

¹⁷ “But he shall acknowledge the son of the hated as the firstborn and give him double portion from all that he has. For he is the first of his strength, and to him belongs the right of firstborn.
