'Belt' in the Bible

"Furthermore, you're aware of what Zeruiah's son Joab did to me and to those two commanders of the armies of Israel, Ner's son Abner and Jether's son Amasa, whom he killed, and how he shed the blood of wartime during times of peace, staining the very belt he wears around his waist and the sandals he wears on his feet.

After Ahab had left, the hand of the LORD came upon Elijah, and he tucked his mantle into his belt and outran Ahab in a race to the city gate of Jezreel.
