Leviticus 8:12 CSB

O – Commentary: 

Moses then poured some of the anointing oil on Aaron’s head … to consecrate him (cf. Ex. 29:7; 30:30; 40:13). The purpose of these anointings was to set apart the tabernacle (Lev. 8:10), the various articles of sacred furniture (vv. 10–11), and the priest who ministered in the sanctuary (v. 12) as most holy to the Lord

“Leviticus,” in The Bible Knowledge Commentary: An Exposition of the Scriptures

The New Strong’s Dictionary of Hebrew and Greek Words 

A – God wanted the priests to be set apart.  All throughout the NT, we are encouraged to do the same.  When we put distance between ourselves and those things, desires or temptations that will trip us, we are saying “I am God’s first.”  

R – Heavenly Father, we choose to consecrate ourselves today.  We are your vessel.  We desire to be holy in mind, body and spirit.  We cannot do this without the blood of Jesus and the forgiveness of our sins daily applied to our lives.  Give us a fresh annointing today to be led by You.
