How were priests annointed or chosen in old testament?

In the Old Testament, priests were typically chosen from the tribe of Levi, specifically from the lineage of Aaron, Moses' brother. Their anointing involved a ritual that included the pouring of sacred oil, symbolizing their consecration and setting apart for service to God. The appointment was often conducted by a designated leader, such as Moses, and was accompanied by specific sacrifices and offerings to signify their dedication to the priestly duties. This selection process underscored the importance of divine appointment and the holiness required for the priestly role.
