and whoever utters slander is a fool.

Proverbs 26:23-26

23 dLike the eglaze
By revocalization; Hebrew silver of dross
covering an earthen vessel
are fervent lips with an evil heart.
24Whoever hates disguises himself with his lips
and harbors deceit in his heart;
25 gwhen he speaks graciously, believe him not,
for there are hseven abominations in his heart;
26though his hatred be covered with deception,
his wickedness will be exposed in the assembly.

Or  Friend, why are you here?
Then they came up and laid hands on Jesus and seized him.
