Psalm 35:14-16 English Standard Version (ESV)

14. I went about as though I grieved for my friend or my brother;as one who laments his mother,I bowed down in mourning.

15. But at my stumbling they rejoiced and gathered;they gathered together against me; wretches whom I did not knowtore at me without ceasing;

16. like profane mockers at a feast,they gnash at me with their teeth.
