'Mourning' in the Bible

Esau hated Jacob because of the blessing with which his father blessed him. Esau said in his heart, "The days of mourning for my father are at hand. Then I will kill my brother Jacob."

All his sons and all his daughters rose up to comfort him, but he refused to be comforted. He said, "For I will go down to Sheol to my son mourning." His father wept for him.

When the inhabitants of the land, the Canaanites, saw the mourning in the floor of Atad, they said, "This is a grievous mourning by the Egyptians." Therefore, its name was called Abel Mizraim, which is beyond the Jordan.
