We continue in this series with a brief look at the priesthood under the law of Moses. Aaron, Moses' brother, and his sons were chosen by the Lord to be priests and they underwent a seven-day consecration ritual to set them apart for God's holy service. The law was very specific about the duties of the priests and the various sacrifices which were to be offered. But the priesthood became corrupted along with the entire nation of Israel, and that situation coupled with the known weakness in the law (the animal sacrifices could not remove sins) moved God to bring about a change in the priesthood along with a change in the law.
