'Mourning' in the Bible

I have not eaten thereof in my mourning, neither have I brought away thereof in uncleanness, nor given thereof for a dead person; I have hearkened to the voice of Jehovah my God; I have done according to all that thou hast commanded me.

And the children of Israel wept for Moses in the plains of Moab thirty days; and the days of weeping and mourning for Moses were ended.
