Charles Ellicott Commentary Isaiah 26:11

"Jehovah, thy hand is lifted up, yet they see not: but they shall see [thy] zeal for the people, and be put to shame; yea, fire shall devour thine adversaries." — Isaiah 26:11 (ASV)

They will not see ... —Better, they did not see, or, they see not, so as to bring out the contrast with the clause that follows. When the arm of Jehovah, the symbol of His power, was simply lifted up for the protection of His people, the evildoers closed their eyes and would not see it. A time will come when judgments shall fall on them, and so they shall be made to see.

Shall be ashamed for their envy at the people. —Better, they shall see (and be ashamed) the jealousy (of God) for the people. They shall understand something of God’s watchful and zealous care for those whom He loves. It shall be seen that it is as a consuming fire (Psalms 79:5) that shall devour His adversaries.
