'Set apart' in the Bible

“You shall take the ram of the ordination and boil its meat in a holy place.

For you are a holy people [set apart] to the Lord your God; the Lord your God has chosen you out of all the peoples on the face of the earth to be a people for His own possession [that is, His very special treasure].

It shall be for the priests who are sanctified of the sons of Zadok, who have kept My charge, and who did not go astray when the children (descendants) of Israel went astray as the [other] Levites did.
