Exodus 23:6

Thou shalt not raise a false report: put not thine hand with the wicked to be an unrighteous witness.

Thou shalt not follow a multitude to do evil; neither shalt thou speak in a cause to decline after many to wrest judgment:

Neither shalt thou countenance a poor man in his cause.

If thou meet thine enemy's ox or his ass going astray, thou shalt surely bring it back to him again.
