'Mourning' in the Bible

Then Esau held a grudge against Jacob on account of the blessing with which his father had blessed him. And Esau said in his heart, "The days of mourning for my father are coming, then I will kill Jacob my brother."

And all his sons and daughters tried to console him, but he refused to be consoled. And he said, "No, I shall go down to my son, to Sheol, mourning." And his father wept for him.

When they came to the threshing floor of Atad, which [was] beyond the Jordan, they lamented there with a very great and sorrowful wailing. And he made a mourning ceremony for his father seven days.

And when the Canaanites, the inhabitants of the land, saw the mourning ceremony at the threshing floor of Atad they said, "This [is] a severe mourning for the Egyptians." Therefore its name was called Abel-Mizraim, which [is] beyond the Jordan.
