John Gill Commentary Deuteronomy 12:25

"Thou shalt not eat it; that it may go well with thee, and with thy children after thee, when thou shalt do that which is right in the eyes of Jehovah." — Deuteronomy 12:25 (ASV)

You shall not eat it, that it may be well with you, and with
your children after you
That they and their posterity might be spared, and continue long, and enjoy much prosperity; for those that eat blood, contrary to this command of God, it is threatened that he would set his face against them, and they should be cut off, (Leviticus 7:27) (17:10) ,

when you shall do that which is right in the sight of the Lord ;
not only observe this command, but all others.
