In order to consecrate something to God’s service, it was anointed with oil. The implements that were designed for use in the Temple were all anointed with oil in order to dedicate them to the Temple. People could also be consecrated- prophets, priests, and kings. They were anointed to separate them for service before God. The prophet spoke God’s words to the people, the priest stood before God representing his people, and the king established God’s laws throughout the land. A person who had been anointed had authority and was to be obeyed.
