Besides the outward signs of mourning, what else was forbidden for the priests?
Leviticus 10:7 (ESV)
7And do not go outside the entrance of the tent of meeting, lest you die, for the anointing oil of the LORD is upon you.” And they did according to the word of Moses.
In addition to the outward signs of mourning, the priests were not allowed to leave the temple precincts during the period of mourning. They must appear to the people as totally devoted to God.
7 And do not go outside the entrance of the tent of meeting, lest you die, for the anointing oil of the LORD is upon you.” And they did according to the word of Moses.
