The worshipers of the temple are those
who are living in Israel.

They and the temple are to be measured
by a rod.

Judgment is about to fall on the world.
Even the worshipers in the temple are
about to be measured and judged.

"Judgment must begin at the house of God."
1 Peter 4:17. This is the time called "Jacob's
trouble" Jeremiah 30:7, when Israel is to
be refined as by fire. (Zechariah 13:9).
