Set apart to serve the Lord as priests.

Romans 1:11 For I long to see you, that I may impart to you some spiritual gift, so that you may be established. A man or woman of God can only impart what they possess. Spirit gives life to spirit. 2 Timothy 1:6 Therefore I remind you to stir up the gift of God which is in you through the laying on of my hands. A man or woman of God cannot give you gift but can stir the gift that God gave you already.
Leviticus 7:35 This is their rightful share. The special gifts presented to the LORD have been reserved for Aaron and his descendants from the time they were set apart to serve the LORD as priests.

Leviticus 8:12 And he poured some of the anointing oil on Aaron’s head and anointed him, to consecrate him.
