8:9-16 The prophet challenges the enemies of the Jews. Their efforts would be vain, and themselves broken to pieces. It concerns us, in time of trouble, to watch against all such fears as put us upon crooked courses for our own security. The believing fear of God preserves against the disquieting fear of man. If we thought rightly of the greatness and glory of God, we should see all the power of our enemies restrained. The Lord, who will be a Sanctuary to those who trust in him, will be a Stone of stumbling, and a Rock of offence, to those who make the creature their fear and their hope. If the things of God be an offence to us, they will undo us. The apostle quotes this as to all who persisted in unbelief of the gospel of Christ, 1Pe 2:8. The crucified Emmanuel, who was and is a Stumbling-stone and Rock of offence to unbelieving Jews, is no less so to thousands who are called Christians. The preaching of the cross is foolishness in their esteem; his doctrines and precepts offend them.
16. Bind up … seal—What Isaiah had before briefly noted by inscribing Maher-shalal-hash-baz in a tablet, fixed up in some public place, he afterwards wrote out more in detail in a parchment roll (Isa 30:8); this he is now to seal up, not merely in order that nothing may be added to, or taken from it, as being complete, but to imply that it relates to distant events, and is therefore to be a sealed and not understood testimony (Isa 6:9, 10), except in part among God's "disciples," that is, those who "sanctify the Lord" by obedient trust (Ps 25:14). Subsequent revelations would afterwards clear up what now was dark. So the Apocalypse explains what in Daniel was left unexplained (compare Da 8:26; 12:9). "The words are closed up and sealed till the time of the end"; but Re 22:10, "Seal not the sayings of the prophecy … for the time is at hand" (compare Re 5:1, 5, 9),
testimony—attested by Uriah and Zechariah (Isa 8:2).
law—the revelation just given, having the force of a law.
disciples—not as Maurer, Uriah and Zechariah (compare Joh 7:17; 15:15).
