'Testify' in the Bible

He does not charge interest when he lends his money. He does not take bribes to testify against the innocent. The one who lives like this will never be upended.

Do not turn me over to my enemies, for false witnesses who want to destroy me testify against me.

Hear, O my people, and I will speak; O Israel, and I will testify against thee: I am God, even thy God.

Hear, O my people, and I will testify unto thee: O Israel, if thou wilt hearken unto me;

Appoint an evil man to testify against him! May an accuser stand at his right side!
