'Slandering' in the Bible

You sit, maligning your brother,slandering your mother’s son.

Let the arrogant be put to shamefor slandering me with lies;I will meditate on Your precepts.

But when some became hardened and would not believe, slandering the Way in front of the crowd, he withdrew from them and met separately with the disciples, conducting discussions every day in the lecture hall of Tyrannus.

This is why, if I come, I will remind him of the works he is doing, slandering us with malicious words. And he is not satisfied with that! He not only refuses to welcome the brothers himself, but he even stops those who want to do so and expels them from the church.
