'Testimony' in the Bible

Then Jesus told him, “See that you don’t tell anyone; but go, show yourself to the priest, and offer the gift that Moses prescribed, as a testimony to them.”

But if he won’t listen, take one or two more with you, so that by the testimony of two or three witnesses every fact may be established.

This good news of the kingdom will be proclaimed in all the world as a testimony to all nations. And then the end will come.

The chief priests and the whole Sanhedrin were looking for false testimony against Jesus so they could put Him to death.
