Boyd’s Bible Dictionary:
(dust). An uncertain place (Mic. 1:10).
Concise Bible Dictionary:
The margin of Micah 1:10 explains the name as “house of dust,” so that there is a play upon the word dust: “in the house of dust roll thyself in the dust.” The LXX read “the house in derision.” It may refer to OPHRAH in Joshua 18:23 and 1 Samuel 13:17, a city in the tribe of Benjamin.
