"So the Lord said to Aaron, 'You and your sons and your father's household with you shall bear the guilt in connection with the sanctuary, and you and your sons with you shall bear the guilt in connection with your priesthood” (v.1).
Aaron, the older brother of Moses, was the first high priest of Israel, an office that would belong to his descendants through the generations. They would be responsible to bring the guilt of themselves and the nation before the Lord, but as to each man, they would not be able to continue in office.
Aaron, his office, and the men who succeeded him, were people who eventually die and pass the priestly duties on to the next in line. Yet even in that temporary state, they lived as an earthly picture of our great High Priest who sits at the right hand of the Father in eternity, the LORD Jesus. And because He lives forever, we now have an unchangeable priesthood" (Hebrews 7:24). Every moment of every day, our Savior is inter-seeding for us. He knows our name, our situations, and He (Himself God), is praying to the Father for us.
The sacrifices presented by Aaron and his sons are no longer necessary because Jesus Christ payed the price "once and for all" when He offered up Himself on the cross.
The Truth: “For such a High Priest was fitting for us, who is holy, harmless, undefiled, separate from sinners, and has become higher than the heavens; who does not need daily, as those high priests, to offer up sacrifices, first for His own sins and then for the people’s, for this He did once for all when He offered up Himself.” (Hebrews 7:26-27)
