2 Samuel 11:26

And when the wife of Uriah heard that Uriah her husband was dead, she mourned for her husband. There is something pathetic in this repetition of the name of the murdered man, and his close relationship with Bathsheba is dwelt upon by his being twice called "her husband," and she "Uriah's wife." Having been the cause of his murder, she is careful to make for him the customary mourning. How long it lasted is uncertain. The mourning for Aaron ( Numbers 20:29 ) and that for Moses ( Deuteronomy 34:8 ) were each for thirty days; while that for Jacob at Atad ( Genesis 50:10 ) and that of the men of Jabesh-Gilead for Saul ( 1 Samuel 31:13 ) lasted only for seven days. Both these, however, were under such exceptional circumstances as made them no rule; but in Ecclesiasticus 22:12 we read, "Seven days do men mourn for him that is dead," and the national lamentation for Judith lasted the same time (Judith 16:24). Probably, however, the mourning of a widow for her husband would last a month.
