Psalms 55:19-21

¹⁹God who has ruled from the beginning will hear me and answer them. Selah. For they refuse to change and don't respect God.

²⁰As for my best friend, he attacked his friends who had no quarrel with him; he broke the promises he had made to them.

²¹What he says is as smooth as butter, but inside he plans war; his words are as soothing as oil, but they cut like sharp swords.
