There is an interesting parallel between the sanctification of the priests of Israel and that of the one High Priest in Heaven. The priests undergo a seven-day ritual after which they are finally consecrated on the eighth day, when the High Priest offers a sacrifice to atone for himself and the people. #yeshua entered Jerusalem to be examined by the people and the priests on the first day of the week. He was examined all that week, arrested, tried, and crucified, atoning for the sins of all people. He then rose from the grave on the eighth day, inaugurating the New Covenant of Jeremiah 31 and being eternally sanctified as its High Priest.
