Bible Verses About Sackcloth: Girt about the loins

Ya'akov tore his clothes and, putting sackcloth around his waist, mourned his son for many days.

His servants said to him, "Here now, we have heard that the kings of the house of Isra'el are merciful kings. If it's all right with you, let's put sackcloth around our waists and ropes on our heads, and go out to the king of Isra'el. Maybe he will spare your life."
