Deuteronomy 21:17-19

New King James Version

¹⁷ But he shall acknowledge the son of the unloved wife as the firstborn ^(A)by giving him a double portion of all that he has, for he ^(B)is the beginning of his strength; ^(C)the right of the firstborn is his.

The Rebellious Son

¹⁸ “If a man has a stubborn and rebellious son who will not obey the voice of his father or the voice of his mother, and who, when they have chastened him, will not heed them, ¹⁹ then his father and his mother shall take hold of him and bring him out to the elders of his city, to the gate of his city.
