I have not eaten thereof in my mourning, neither have I put away thereof, being unclean, nor given thereof for the dead: 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: so the days of weeping in the mourning for Moses were ended.
