do you see what the elders of the house of Israel are doing in the dark?

God is commanding Ezekiel to look at what the elders are doing. Alternate translation: "look at what the elders of the house of Israel are doing in the dark." (See: rc://en/ta/man/translate/figs-rquestion)

the house of Israel

The word "house" is a metonym for the family that lives in the house, in this case the Israelites, the descendants of Jacob over many years. See how you translated this in Ezekiel 3:1. Alternate translation: "the Israelites" or "the Israelite people group" (See: rc://en/ta/man/translate/figs-metonymy)

the hidden chamber of his idol

"the room where no one can see him worship his idol"
