'Mourning' in the Bible

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

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

And they came to the threshing-floor of Atad, which is beyond the Jordan, and there they lamented with a very great and sore lamentation: and he made a mourning for his father seven days.

And when the inhabitants of the land, the Canaanites, saw the mourning in the floor of Atad, they said, This is a grievous mourning to the Egyptians: wherefore the name of it was called Abel-mizraim, which is beyond the Jordan.
