'Belt' in the Bible

"You know what Joab son of Zeruiah did to me -- how he murdered two commanders of the Israelite armies, Abner son of Ner and Amasa son of Jether. During peacetime he struck them down like he would in battle; when he shed their blood as if in battle, he stained his own belt and the sandals on his feet.

Now the Lord energized Elijah with power; he tucked his robe into his belt and ran ahead of Ahab all the way to Jezreel.
