Exodus 29:5-9 meaning

Moses was now instructed by the LORD to take the garments, and put on Aaron the garments described in Chapter 28. First, the high priest's clothes were to be put on Aaron:

• The tunic, which served as an undershirt
• The robe of the ephod, which was worn underneath the ephod
• The ephod itself
• The breastpiece
• Finally, gird him with the skillfully woven band of the ephod

Then, the headdress was to be placed on him.

• The turban
• The holy crown on the turban. Leviticus 8:9 tells us that the holy crown that was placed on the turban was the same as the golden plate engraved with the words "holy to the Lord" (Exodus 28:36).

Finally, Moses was to take the anointing oil and pour it on Aaron's head and anoint him. This had the effect of setting Aaron apart and commissioning him to serve the LORD in the tabernacle as God's priest.

After the anointing of Aaron into the role of high priest, his sons needed to be consecrated into the priesthood. To do this, Moses was instructed to bring his sons forward to be clothed. He first put tunics on them, then he was to gird them with sashes and bind caps on them.

The result of the ceremony was that they shall have the priesthood by a perpetual statute. This means that Aaron and his descendants were chosen by the LORD to be priests to serve Him and the people in their worship. During the Messianic kingdom, this lineage will be restricted to the "Sons of Zadok" who "kept charge of My sanctuary when the sons of Israel went astray from Me" (Ezekiel 44:15).

The last phrase summarizes this section. All of the actions were done to ordain Aaron and his sons. The word ordain translates the Hebrew phrase "fill the hands." It refers to all of the activities that would "fill the hands" of the priests to perform in the service of the LORD.
