'Faithful Witness' in the Bible

like the moon, established forever,a faithful witness in the sky.”Selah

And they said to Jeremiah, “As for every word the Lord your God sends you to tell us, if we don’t act accordingly, may the Lord be a true and faithful witness against us.

and from Jesus Christ, the faithful witness, the firstborn from the dead and the ruler of the kings of the earth.To Him who loves us and has set us free from our sins by His blood,

I know where you live—where Satan’s throne is! And you are holding on to My name and did not deny your faith in Me, even in the days of Antipas, My faithful witness who was killed among you, where Satan lives.
