Isaiah 50:11

All ye that kindle a fire. — The words obviously point to any human substitute for the Divine light, and thus include the two meanings which commentators have given them: (1) Man’s fiery wrath, that worketh not the righteousness of God; and (2) man’s attempt to rest in earthly comforts or enjoyments instead of in the light and joy that comes from God.

That compass yourselves about with sparks. — The words are rendered by many commentators, gird yourselves with burning darts, or firebrands, i.e., with calumnies and execrations as your weapons of warfare (Comp. Ephesians 6:16.)

Ye shall lie down in sorrow. — The words point to a death of anguish, perhaps to the torment that follows death (comp. Luke 16:24), as the outcome of the substitution of the earthly for the heavenly light.
