'But let justice roll down like waters and _______like an overflowing stream'

The missing word in the phrase is "righteousness." This phrase is a quotation from the Book of Amos in the Old Testament of the Bible. In this passage, the prophet Amos is calling for justice and righteousness to be established in society, so that all people can be treated fairly and with equity. The metaphor of water is used to convey the idea that justice and righteousness should flow continuously and abundantly, like the waters of a river or a stream. It should not be a mere trickle or a temporary solution, but rather a constant and overwhelming force that cleanses and purifies society. Thus, the phrase "Let justice roll down like waters and righteousness like an overflowing stream" is a powerful call to action for people to work towards creating a more just and equitable society, where everyone is treated with fairness and dignity.
