Thou shall not eat it, that it may be well with thee, and with thy children after thee,.... 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, Lev 7:27, when thou shall do that which is right in the sight of the Lord; not only observe this command, but all others.
