Bible Verses About Children: Partiality among, forbidden

If a man haue two wiues, one loued and another hated, and they haue borne him children, both the loued and also the hated: if the first borne be the sonne of the hated,

Then when the time commeth, that hee appointeth his sonnes to be heires of that which he hath, he may not make the sonne of the beloued first borne before the sonne of the hated, which is the first borne:

But he shall acknowledge the sonne of the hated for the first borne, and giue him double portion of all that he hath: for hee is the first of his strength, and to him belongeth the right of the first borne.
