You must not leave the body hanging on the pole overnight. Be sure to bury it that same day, because anyone who is hung on a pole is under God's curse. You must not desecrate the land the LORD your God is giving you as an inheritance.
His body shall not remain all night upon the tree, but you shall surely bury him on the same day, for a hanged man is accursed by God. Thus you shall not defile your land which the Lord your God gives you for an inheritance. [Gal. 3:13.]AMP
His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.
He must acknowledge the son of his unloved wife as the firstborn by giving him a double share of all he has. That son is the first sign of his father's strength. The right of the firstborn belongs to him.
But he shall acknowledge the son of the disliked as the firstborn by giving him a double portion of all that he has, for he was the first issue of his strength; the right of the firstborn is his.
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.
