In Ezekiel 8:16, what were about 25 men at the temple entrance bowing down to worship?

Answer: The sun

With their backs to the temple of the LORD and their faces toward the east, they were bowing to the east in worship of the sun.

“So He brought me to the inner court of the house of the LORD, and there at the entrance to the temple of the LORD, between the portico and the altar, were about twenty-five men with their backs to the temple of the LORD and their faces toward the east; and they were bowing to the east in worship of the sun.”— Ezekiel 8:16 (BSB)
