'Testimony' in the Bible

and all were bearing testimony to him, and were wondering at the gracious words that are coming forth out of his mouth, and they said, 'Is not this the son of Joseph?'

And he charged him to tell no one, 'But, having gone away, shew thyself to the priest, and bring near for thy cleansing according as Moses directed, for a testimony to them;'

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

and it shall become to you for a testimony.

and they said, 'What need yet have we of testimony? for we ourselves did hear it from his mouth.'
