Bible Verses About Priests: Were to live by the altar as they had no inheritance

¶ The priests the Levites, and all the tribe of Levi, shall have no part nor inheritance with Israel: they shall eat the offerings of the LORD made by fire, and his inheritance.

Therefore shall they have no inheritance among their brethren: the LORD is their inheritance, as he hath said unto them.

Do ye not know that they which minister about holy things live of the things of the temple? and they which wait at the altar are partakers with the altar?
