Every firstling that is born among thy kine and among thy sheep that is a male, thou shalt hallow to Jehovah thy God: thou shalt do no work with the firstling of thy kine, nor shear the firstling of thy sheep.

If a man have two wives, one beloved, and one hated, and they have borne him children, both the beloved and the hated, and the firstborn son be hers that was hated;

Children that are born to them shall come into the congregation of Jehovah in the third generation.
