Leviticus 8

The Lord said to Moses, “Bring Aaron and his sons, their garments, the anointing oil, the bull for the sin offering, the two rams and the basket containing bread made without yeast, and gather the entire assembly at the entrance to the tent of meeting.” Moses did as the Lord commanded him, and the assembly gathered at the entrance to the tent of meeting. Moses said to the assembly, “This is what the Lord has commanded to be done.” Then Moses brought Aaron and his sons forward and washed them with water. He put the tunic on Aaron, tied the sash around him, clothed him with the robe and put the ephod on him. He also fastened the ephod with a decorative waistband, which he tied around him. He placed the breastpiece on him and put the Urim and Thummim in the breastpiece. Then he placed the turban on Aaron’s head and set the gold plate, the sacred emblem, on the front of it, as the Lord commanded Moses. Then Moses took the anointing oil and anointed the tabernacle and everything in it, and so consecrated them. He sprinkled some of the oil on the altar seven times, anointing the altar and all its utensils and the basin with its stand, to consecrate them. He poured some of the anointing oil on Aaron’s head and anointed him to consecrate him. Then he brought Aaron’s sons forward, put tunics on them, tied sashes around them and fastened caps on them, as the Lord commanded Moses. He then presented the bull for the sin offering, and Aaron and his sons laid their hands on its head. Moses slaughtered the bull and took some of the blood, and with his finger he put it on all the horns of the altar to purify the altar. He poured out the rest of the blood at the base of the altar. So he consecrated it to make atonement for it. Moses also took all the fat around the internal organs, the long lobe of the liver, and both kidneys and their fat, and burned it on the altar. But the bull with its hide and its flesh and its intestines he burned up outside the camp, as the Lord commanded Moses. He then presented the ram for the burnt offering, and Aaron and his sons laid their hands on its head. Then Moses slaughtered the ram and splashed the blood against the sides of the altar. He cut the ram into pieces and burned the head, the pieces and the fat. He washed the internal organs and the legs with water and burned the whole ram on the altar. It was a burnt offering, a pleasing aroma, a food offering presented to the Lord, as the Lord commanded Moses. He then presented the other ram, the ram for the ordination, and Aaron and his sons laid their hands on its head. Moses slaughtered the ram and took some of its blood and put it on the lobe of Aaron’s right ear, on the thumb of his right hand and on the big toe of his right foot. Moses also brought Aaron’s sons forward and put some of the blood on the lobes of their right ears, on the thumbs of their right hands and on the big toes of their right feet. Then he splashed blood against the sides of the altar. After that, he took the fat, the fat tail, all the fat around the internal organs, the long lobe of the liver, both kidneys and their fat and the right thigh. And from the basket of bread made without yeast, which was before the Lord, he took one thick loaf, one thick loaf with olive oil mixed in, and one thin loaf, and he put these on the fat portions and on the right thigh. He put all these in the hands of Aaron and his sons, and they waved them before the Lord as a wave offering. Then Moses took them from their hands and burned them on the altar on top of the burnt offering as an ordination offering, a pleasing aroma, a food offering presented to the Lord. Moses also took the breast, which was his share of the ordination ram, and waved it before the Lord as a wave offering, as the Lord commanded Moses. Then Moses took some of the anointing oil and some of the blood from the altar and sprinkled them on Aaron and his garments and on his sons and their garments. So he consecrated Aaron and his garments and his sons and their garments. Leviticus‬ ‭8‬:‭1‬-‭30‬ ‭NIV‬‬

God gives Moses the instructions on how to consecrate (set apart, make holy) Aaron and his sons as priests.  Notice in verses 23 and 24 that Moses put ram’s blood on the priests’ right ears, the thumbs of their right hands, and the big toes of their right feet.  The significance of God’s instruction to Moses to put the blood on the right side of the body is that in the culture of that day, the right side represented power and favor.  The ear was anointed so the priests would hear clearly and not be deceived, the thumb so that what they laid their hands upon would be blessed, and the right toe so that they would walk along the path that God had ordained for their lives.  Just as Aaron and his sons were set apart for God’s use, we believers are also set apart for holy use.  We can’t, however, do it without the help of the Holy Spirit guiding us.  We should ask God to give us ears to clearly understand what He is saying, and not just what our flesh wants to hear.  We must ask Him to sanctify our hands to do what is right and lead our feet to walk on the correct path.
