'Witness' in the Bible

And all bore witness to him, and wondered at the words of grace which were coming out of his mouth. And they said, Is not this the son of Joseph?

And as many as may not receive you, going forth from that city, shake off even the dust from your feet for a witness against them.

Ye bear witness then, and consent to the works of your fathers; for they killed them, and ye build their sepulchres.

Thou knowest the commandments: Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Honour thy father and thy mother.

And they said, What need have we any more of witness, for we have heard ourselves out of his mouth?
