'Witness' in the Bible

For out of the heart come evil thoughts, murders, adulteries, fornications, thefts, false witness, slanders.

Then he *said to Him, “Which ones?” And Jesus said, “You shall not commit murder; You shall not commit adultery; You shall not steal; You shall not bear false witness;

So you testify against yourselves, that you are sons of those who murdered the prophets.

This gospel of the kingdom shall be preached in the whole world as a testimony to all the nations, and then the end will come.
