Isaiah 21:11 (a) The meaning of this word is "the burden of silence." Since there is no sound from Heaven, no voice from GOD, no expressions from eternity except what we find in the Bible, the prophet was troubled about it. His trouble made him ask the question, "What of the night?" Few ever ask, "What of the light?", or "What of Heaven?" Many ask, is there a hell? but no one asks, is there a Heaven? This silence is not broken by audible sounds, but is certainly broken by the Word of GOD.
