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

i would say that these are the two thesis statements best for a literary analysis essay on recurring themes in shakespeare's romeo and juliet:

1.  in romeo and juliet, shakespeare demonstrates that love comes in a variety of forms, be it romantic, familial, or between friends.

2.  shakespeare explores the struggle for identity through the character of juliet in his play romeo and juliet.

the other theses aren't reoccurring in this play.
