'Sanctifying' in the Bible

Sons of Amram: Aaron and Moses; and Aaron is separated for his sanctifying the holy of holies, he and his sons -- unto the age, to make perfume before Jehovah, to serve Him, and to bless in His name -- unto the age.

and all that Samuel the seer, and Saul son of Kish, and Abner son of Ner, and Joab son of Zeruiah sanctified, every one sanctifying any thing -- it is by the side of Shelomith and his brethren.
