When Grief is Prohibited

(4) Moses called Mishael and Eltzaphan, sons of Uzziel the uncle of Aaron, and said to them, “Come forward and carry your kinsmen away from the front of the sanctuary to a place outside the camp.” (5) They came forward and carried them out of the camp by their tunics, as Moses had ordered. (6) And Moses said to Aaron and to his sons Eleazar and Itamar, “Do not bare your heads and do not tear your clothes, lest you die and anger strike the whole community. But your kinsmen, all the house of Israel, shall mourn the calamity that the ETERNAL has wrought. (7) And so do not go outside the entrance of the Tent of Meeting, lest you die, for God’s anointing oil is upon you.” And they did as Moses had bidden.

You shall rejoice in your festival, with your son and daughter, your male and female slave, the Levite, the stranger, the orphan, and the widow in your communities.

A mourner does not comport himself in mourning during a festival, as it is said: You shall rejoice in your festival. And if his mourning began before the festival, a positive commandment incumbent on the community overrides one incumbent on him as an individual; if his mourning began just during the festival, an individual commandment cannot come and override one of the public.

For the Sages taught as follows with regard to this issue: Shabbat counts as one of the days of mourning, although one may not mourn on it and it does not interrupt the mourning period, which continues after Shabbat. The festivals, on the other hand, interrupt the mourning period, so that if one began mourning before such a Festival, then the mourning period is canceled by the festival.

If the death occurred before the holiday and he observed mourning - even for a single hour - before the holiday, shiva is no longer applicable...

If one heard distant news of a death on Shabbat or a holiday, he observes no mourning practices, even in private. Then, after Shabbat or the holiday, he will observe a single hour of mourning, and it is sufficient.

All whom one mourns, he mourns with him if a relative [of the latter] dies. But this is only in his presence; it is not necessary to conduct mourning rituals when not in his presence. ... Rem"a: And there are those who say that nowadays, the practice is to be lenient in this mourning with those for whom one would mourn, because this is only for the honor of the mourners...in any event, the practice is that all the relatives of the deceased...indicate a little bit of mourning for themselves...

(11) When Job’s three friends heard about all these calamities that had befallen him, each came from his home — Eliphaz the Yemenite, Bildad the Shuhite, and Zophar the Na'amatite. They met together to go and console and comfort him. (12) When they saw him from a distance, they could not recognize him, and they broke into loud weeping; each one tore his robe and threw dust into the air onto his own head. (13) They sat with him on the ground for seven days and seven nights. None spoke a word to him, for they saw how very great was his suffering.
