'Tongue' in the Bible

“They bend their tongue like their bow;[Their] lies and not truth prevail and grow strong in the land;For they proceed from evil to evil,And they do not know and understand and acknowledge Me,” says the Lord.

“Their tongue is a murderous arrow;It speaks deceit;With his mouth one speaks peace to his neighbor,But in his heart he lays traps and waits in ambush for him.

Then [my enemies] said, “Come and let us work out schemes against Jeremiah. Surely the law is not going to be lost to the priest [as Jeremiah predicts], nor the counsel from the wise, nor the word from the prophet. Come and let us strike him with our tongue [by making charges against him before the king], and let us ignore anything he says.”
