'Mourning' in the Bible

At the evening offering I got up from my mourning posture and, with my garment and robe torn, I fell down on my knees and I spread out my palms to Yahweh my God

Ezra then went from the house of God and walked to the chamber of Jehohanan son of Eliashib, where he spent the night. He did not eat food or drink water, because he was mourning over the unfaithfulness of the exiles.
