Jeremiah 11:19

But I was like a lamb or an ox that is brought to the slaughter, with never an inkling of the evil intention of his own familiar friends; and I knew not that they had devised devices against me, saying, Let us destroy the tree with the fruit thereof and let us cut him off from the land of the living that his name may be no more remembered. They wanted to bring ruin, if possible, death, to Jeremiah and cause his teaching to be forgotten. Therefore the prophet calls upon the Lord for vengeance in his just cause.
