'Consecrating' in the Bible

gold for the things of gold, silver for the things of silver, that is, for all the work to be done by craftsmen. Now who is willing to consecrate himself today to the Lord?”

It is like the precious oil [of consecration] poured on the head,Coming down on the beard,Even the beard of Aaron,Coming down upon the edge of his [priestly] robes [consecrating the whole body].

“Before I formed you in the womb I knew you [and approved of you as My chosen instrument],And before you were born I consecrated you [to Myself as My own];I have appointed you as a prophet to the nations.”
