Leviticus 17:12

Therefore I said unto the children of Israel, no soul of you
shall eat blood
Great or small as Jarchi observes, for the reason above given; which, though not expressed before, was the true reason of this law, which had been given before, and now repeated; see ( Leviticus 3:17 ) ( Leviticus 7:26 Leviticus 7:27 ) ;

neither shall any stranger that sojourneth among you eat blood;
any proselyte of righteousness; this is not observed before.
