'Set Apart' in the Bible

All these, who had been set apart as gatekeepers at the entrances, numbered 212 and had been enrolled by genealogies in their villages.

The descendants of Amram included Aaron and Moses. Aaron had been set apart to consecrate the most holy things, with the intent that he and his sons should present offerings in the LORD's presence forever, ministering to him and pronouncing blessings in his name forever.
