'Upper Room' in the Bible

Woe [to the one who] builds his house without righteousness, and his upper rooms without justice. His fellow countryman, he works for nothing, and he does not give to him his wages.

Who says 'I will build for myself a spacious house with large upper rooms,' and he cuts windows for it, and [it is] paneled with cedar, and he paints [it] with vermilion.
