Plumb Line

Holman Bible Dictionary

A cord with a weight (usually metal or stone) attached to one end. The plumb line would be dangled beside a wall during its construction to assure vertical accuracy. Prophets spoke of the measurement God would use on the nation (Isaiah 28:17; Amos 7:7-8 ). Israel had been built straight, but, because it was out of line, it would be destroyed.
