Matthew Henry Commentary Isaiah 24:13-15

"For thus shall it be in the midst of the earth among the peoples, as the shaking of an olive-tree, as the gleanings when the vintage is done. These shall lift up their voice, they shall shout; for the majesty of Jehovah they cry aloud from the sea. Wherefore glorify ye Jehovah in the east, even the name of Jehovah, the God of Israel, in the isles of the sea." — Isaiah 24:13-15 (ASV)

There shall be a remnant preserved from the general ruin, and it shall be a devout and pious remnant. These few are dispersed, like the gleanings of the olive tree, hidden under the leaves. The Lord knows those who are His; the world does not.

When the merriment of worldly, carnal people ceases, the joy of the saints is as vibrant as ever, because the covenant of grace—the fountain of their comforts and the foundation of their hopes—never fails.

Those who rejoice in the Lord can rejoice in tribulation, and by faith may triumph when all around them are in tears. They encourage their fellow sufferers to do likewise, even those who are in the furnace of affliction or in the valleys—low, dark, muddy places.

In every fire, even the hottest, in every place, even the remotest, let us maintain our good thoughts of God. If none of these trials move us, then we glorify the Lord in the fires.
