'Belt' in the Bible

It shall happen that instead of sweet spices, there shall be rottenness; instead of a belt, a rope; instead of well set hair, baldness; instead of a robe, a wearing of sackcloth; and branding instead of beauty.

None shall be weary nor stumble among them; none shall slumber nor sleep; neither shall the belt of their waist be untied, nor the latchet of their shoes be broken:

Righteousness will be the belt of his waist, and faithfulness the belt of his waist.

and I will clothe him with your robe, and strengthen him with your belt. I will commit your government into his hand; and he will be a father to the inhabitants of Jerusalem, and to the house of Judah.
