'Priest's' in the Bible

thus says the Lord God, ‘Remove the turban and take off the crown; things shall not remain as they have been. Exalt that which is low and abase the high.

They must not marry a widow or a divorcee, but they may marry a virgin from the house of Israel or a widow who is a priest's widow.

And the first of all the firstfruits of all things, and every oblation of all, of every sort of your oblations, shall be the priest's: ye shall also give unto the priest the first of your dough, that he may cause the blessing to rest in thine house.
