'Ropes' in the Bible

And his servants said to 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; perhaps he will save thy life.

And they girded sackcloth on their loins, and ropes on their heads, and came to the king of Israel, and said, Thy servant Ben-Hadad says, I pray thee, let me live. And he said, Is he yet alive? he is my brother.
