'Witness' in the Bible

And I will require reliable witnesses as a witness for me: Uriah the priest and Zechariah son of Jeberekiah."

And it will be a sign and a witness to Yahweh of hosts in the land of Egypt; when they cry out to Yahweh because of oppressors, he will send them a savior and a {defender}, and he will deliver them.

Look! I made him a witness to [the] peoples, a leader and a commander [for the] peoples.
