What did MLK mean when he said "justice rolls down like waters, and righteousness like a mighty stream" I looked it up online but I didn't understand any of the meanings online

Explanation:

Martin Luther King Jr. understood that life-giving water holds potential to be placid and potent, resilient and renewing, fluid yet forceful. In his historic “ I Have a Dream ” speech during the 1963 March on Washington, King declared: “We will not be satisfied until justice rolls down like waters and righteousness like a mighty stream.”

ps. i did found this i did not come up with this i do not want to take credit

“thy baited hooks shall tangle me no more.”

“hath taught me to set in trifles no store,”

“me lusteth no longer rotten boughs to climb.”

the author is showing that it is the insatisfaction of basic needs that brings about the protests such as the strikes.if workers do not earn enough to buy food and feed their families and themselves in order to continue working, what is the use of working? besides, another message from the author is that of the owners of factories should be worried about ensuring their furure by having a second and third generation of workers in their industries.if they do not hear the workers demands, they will not have any more workers to make their pockets full.
