'Consecrated' in the Bible

These are the names of the sons of Aaron, the anointed priests, who were consecrated to exercise the priesthood.

All the days of the vow of his separation there shall no razor come upon his head; until the days be fulfilled, that he hath consecrated himself to Jehovah, he shall be holy; he shall let the locks of the hair of his head grow.

All the days that he hath consecrated himself to Jehovah, he shall come near no dead body.
