'Be Holy' in the Bible

“You must not cut his hair throughout the time of his vow of consecration. He must be holy until the time is completed during which he consecrates himself to the Lord; he is to let the hair of his head grow long.

This way you will remember and obey all My commands and be holy to your God.

You are to eat it as a most holy offering. Every male may eat it; it is to be holy to you.
