The light shall be dark in his tabernacle. This is not, as Rosenmuller asserts, a mere repetition of the thought contained in the preceding verse with a change of terms, and a variation of metaphor. It is a denunciation of woe to the whole house of the ungodly man, not to himself only.
As Schultens says, "Lumen ob-tenebratum in tentorio est fortuna domus extincta." And his candle shall be put out with him; rather, as in the Revised Version, his!amp above him shall be put out; i.e. the lamp which swings above him in his tent, or in his chamber, shall be extinguished.
Darkness shall fall upon the whole house of the wicked man.
