Jeremiah 9:4-8

“Let everyone be on guard against his neighbor, And do not trust any brother; Because every brother deals craftily, And every neighbor goes about as a slanderer. Everyone deceives his neighbor And does not speak the truth, They have taught their tongue to speak lies; They weary themselves committing iniquity. Your dwelling is in the midst of deceit; Through deceit they refuse to know Me,” declares the LORD. Therefore thus says the LORD of hosts, “Behold, I will refine them and assay them; For what else can I do, because of the daughter of My people? Their tongue is a deadly arrow; It speaks deceit; With his mouth one speaks peace to his neighbor, But inwardly he sets an ambush for him.
