'House tops' in the Bible

On all the housetops in Moab and in all its public squares there will be nothing but mourning. For I will break Moab like an unwanted jar. I, the Lord, affirm it!

What I say to you in the dark, tell in the light, and what is whispered in your ear, proclaim from the housetops.

So then whatever you have said in the dark will be heard in the light, and what you have whispered in private rooms will be proclaimed from the housetops.
