"Until the death of the High Priest": He who brings down the Divine Presence, etc. Another explanation is that he should have prayed, etc. It is difficult to understand the second explanation. One could say that the second explanation is more consistent, because according to the first explanation, it would not have been permissible to stand before the High Priest forever, even if another High Priest succeeded him, since one brings down the Divine Presence and the other removes it, as stated in the verse, "For your sword will be lifted over him," meaning that it is not fitting for the one who shortens (the time) to be in the position of the one who lengthens it. Therefore, the second explanation is that the High Priest was considered deficient in not praying to prevent this mishap, which is why it refers back to his death and to the days of the second High Priest.
