'Witness' in the Bible

The expression of their faces bears witness against them,And they display their sin like Sodom;They do not even conceal it.Woe to them!For they have brought evil on themselves.

It will become a sign and a witness to the Lord of hosts in the land of Egypt; for they will cry to the Lord because of oppressors, and He will send them a Savior and a Champion, and He will deliver them.

Now go, write it on a tablet before themAnd inscribe it on a scroll,That it may serve in the time to comeAs a witness forever.

“Behold, I have made him a witness to the peoples,A leader and commander for the peoples.
