Thou shalt not raise a false report: put not thine hand with the wicked to be an unrighteous witness.
2 Timothy 3:3
Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good,
And the soldiers likewise demanded of him, saying, And what shall we do? And he said unto them, Do violence to no man, neither accuse [any] falsely; and be content with your wages.

Yea, mine own familiar friend, in whom I trusted, which did eat of my bread, hath lifted up [his] heel against me.
An evil disease, [say they], cleaveth fast unto him: and [now] that he lieth he shall rise up no more.
All that hate me whisper together against me: against me do they devise my hurt.
And if he come to see [me], he speaketh vanity: his heart gathereth iniquity to itself; [when] he goeth abroad, he telleth [it].
Mine enemies speak evil of me, When shall he die, and his name perish?
Thou shalt not go up and down [as] a talebearer among thy people: neither shalt thou stand against the blood of thy neighbour: I [am] the LORD.
Keep thee far from a false matter; and the innocent and righteous slay thou not: for I will not justify the wicked.
1 Peter 4:14
If ye be reproached for the name of Christ, happy [are ye]; for the spirit of glory and of God resteth upon you: on their part he is evil spoken of, but on your part he is glorified.
