Did Moses act as a priest?

Moses was called a 'priest' occasionally when he needed to perform certain acts (Psalm 99:6/Exodus 24:6), like when he called upon God's name(YHWH) interceding for Israel(Numbers 14:13-20), but that was not his normal position(Exodus 40:12+13/Hebrews 5:4). He had a different job. He was the 'anointed' of God(Hebrews 11:23-26)prefiguring Jesus(Acts 3:20-22), the 'mediator of the law covenant' between God and the Israelites, and had the responsibility of writing out the law(2Chronicles 34:14), seeing that it was delivered and carried out (Leviticus 21:1-4+10+11), and arranging for Aaron and his sons to act a priests (Leviticus 8:1-10:20)(Exodus 25:1+Exodus 28:1+40-43/Numbers 3:10) .
