'Serve' in the Bible

‘This is that which is consecrated to Aaron and that which is consecrated to his sons from the offerings by fire to the Lord, in that day when he presented them to serve as priests to the Lord.

So the priest who is anointed and ordained to serve as priest in his father’s place shall make atonement: he shall thus put on the linen garments, the holy garments,

He shall be with you as a hired man, as if he were a sojourner; he shall serve with you until the year of jubilee.
