Aaron was anointed with oil during his consecration which made him the LORD’s anointed. It is important to notice this because the word “anointed” in the Greek language of the New Testament is “Christ”, the title given to Jesus because he is the LORD’s anointed.

For example, a bullock and rams were sacrificed to represent the sacrifice of Christ. Here is a vital distinction between Aaron and Jesus. While Aaron as a High Priest sacrificed animals, Jesus as a High Priest sacrificed himself. The apostle furthermore emphasised the superiority of the sacrifice of Jesus over that of bullocks and other animals Hebrews 9:12-14.Waiting for response for Hebrews 9:12-14
