Genesis 37:34

"And Reuben returned unto the pit; and, behold, Joseph was not in the pit; and he rent his clothes."

"And David said to Joab, and to all the people that were with him, Rend your clothes, and gird you with sackcloth, and mourn before Abner. And king David himself followed the bier."

"And David lifted up his eyes, and saw the angel of the LORD stand between the earth and the heaven, having a drawn sword in his hand stretched out over Jerusalem. Then David and the elders of Israel, who were clothed in sackcloth, fell upon their faces."

"And it came to pass, when Ahab heard those words, that he rent his clothes, and put sackcloth upon his flesh, and fasted, and lay in sackcloth, and went softly."

"What think ye? They answered and said, He is guilty of death."

"I made sackcloth also my garment; and I became a proverb to them."

"And his servants said unto him, Behold now, we have heard that the kings of the house of Israel are merciful kings: let us, I pray thee, put sackcloth on our loins, and ropes upon our heads, and go out to the king of Israel: peradventure he will save thy life."

"Tremble, ye women that are at ease; be troubled, ye careless ones: strip you, and make you bare, and gird sackcloth upon your loins."
