Zephaniah 1:11

Zephaniah called the inhabitants of the Mortar, the market or business district of Jerusalem, to wail because judgment was coming. This section of Jerusalem may have received the name "mortar" (bowl) because it lay in the somewhat geographically depressed Tyropoeon Valley. The Canaanites who did business there would fall silent because business would cease. Those who weighed silver as they conducted commercial transactions would also perish from the city.
