'Bear Witness' in the Bible

Unto the same, do all the prophets bear witness, That, remission of sins, is to be received through his name, by every one that believeth on him.

But, on the following night, the Lord, standing over him, said - Be of good courage! for, as thou hast fully borne witness of the things concerning me in Jerusalem, so must thou, in Rome also, bear witness.

inasmuch as they were aforetime observing me, from the outset, - if they please to bear witness, - that, according to the strictest sect of our own religion, I lived, a Pharisee.
