Leviticus 21:12 Commentary - Ellicott's Commentary for English Readers (Old and New Testaments)
(12) Neither shall he go out of the sanctuary.—Better, and he shall not go out of the sanctuary as in Lev. 10:7. When the tidings of the death of a parent is brought to him during the service, he must not desist from the service and quit the sanctuary, lest it should appear that he has a greater regard for the dead than for the service of the living God. The difference between the ordinary priest and the high priest in this respect was, that when the former heard, during the service, of the death of any one of the seven relations for whom he had to mourn, he was obliged to discontinue the service, though he too could not leave the precincts of the sanctuary; whilst the former, under these circumstances, was bound to continue the service. The former, by becoming a mourner, profaned the service if he continued it; the latter never became a mourner, and hence profaned the service if he discontinued it.
