'Witness' in the Bible

Instead, it is to be a witness between us and you, and between the generations after us, so that we may carry out the worship of the Lord in His presence with our burnt offerings, sacrifices, and fellowship offerings. Then in the future, your descendants will not be able to say to our descendants, ‘You have no share in the Lord!’

We thought that if they said this to us or to our generations in the future, we would reply: Look at the replica of the Lord’s altar that our fathers made, not for burnt offering or sacrifice, but as a witness between us and you.

So the Reubenites and Gadites named the altar: It is a witness between us that the Lord is God.

And Joshua said to all the people, “You see this stone—it will be a witness against us, for it has heard all the words the Lord said to us, and it will be a witness against you, so that you will not deny your God.”
