Then he put the tunic on Aaron and wrapped his waist with the sash, and clothed him with the robe and put the ephod on him; and he wrapped his waist with the artistic band of the ephod, with which he fitted it to him.
-- Leviticus 8:7
God chose these clothes for the chief priests who would serve in the temple, in their turn, for the next 1,000 years. Most of the time the people would not see him because he would be in the Holy Place in the temple. They did this so they were suitably dressed in the presence of God. If you think about it, why the special clothes because God sees us everywhere, naked or clothed. The point was that they were required to show proper respect before God, and to do that, they dressed as he told them to and followed the procedure to the letter. We need to honor God too, but happily, not with rituals.
So Moses did just as the Lord commanded him. When the congregation was assembled at the doorway of the tent of meeting, 5 Moses said to the congregation, “This is the thing which the Lord has commanded us to do.” 6 Then Moses had Aaron and his sons come near, and he washed them with water.
-- Leviticus 8:4-6
The people had donated all the stuff and skilled people had built the tabernacle. Now it was all up and they were ready to start to offer the sacrifices. God told them how important all of this was and how it would be done. This verse tells how Arron and his sons were prepared. They washed them in front of everyone. I don’t know how embarrassing it all was, but there was no argument. God said to do it and they did it. It is what is supposed to happen when we get clear instructions from God.
I will offer You a sacrifice of thanksgiving, And call upon the name of the Lord. 18 I will pay my vows to the Lord, May it be in the presence of all His people, In the courtyards of the Lord’s house, In the midst of you, Jerusalem! Praise the Lord!
-- Psalm 116:17-18
If you have what could be called, your own personal watershed experience, you would want to share it. You have a baby so you want everyone to know. You survived cancer, you want to share the news. This is one of those things, probably the biggest in your life, so you want the biggest audience possible. He has chosen the biggest place where people care about that type of thing. We need to find places to share our story about how Jesus saved us and how he continues to live in us every day. People need to hear that God is faithful, because that information changes lives.
