Fire-breather

The two witnesses of Revelation 11 are implicitly linked to Elijah adn Moses, Joshua and Zerubbabel, the two olive trees in Zechariah’s vision, and the lampstands of Zechariah’s vision.

But the fire-breathing part (v. 5) is not so directly linked with these Old Testament precedents. Yahweh breathes fire (2 Samuel 22:9), but Moses doesn’t in a literal sense, and neither does Elijah.

The closest Old Testament precedent seems to be Jeremiah 5:14, where the Lord promises to put His words into Jeremiah’s mouth like fire, and to make the people like wood, who will be consumed in the fire that te prophet breathes out against them. That fits the context in Revelation 11, which is a prophecy against the city and temple of Jerusalem.
