Charles Ellicott Commentary Isaiah 25:8

"He hath swallowed up death for ever; and the Lord Jehovah will wipe away tears from off all faces; and the reproach of his people will he take away from off all the earth: for Jehovah hath spoken it." — Isaiah 25:8 (ASV)

He will swallow up ... —The verb is the same as the “destroy” of Isaiah 25:7. The words are an echo of the earlier promise of Hosea 13:14. They are, in their turn, re-echoed in the triumph-anthem of St. Paul in 1 Corinthians 15:54. The clause, the Lord God shall wipe away tears, is in the same way reproduced in Revelation 7:17; Revelation 21:4.

The rebuke of his people ... —The taunt to which they were exposed in the time of their affliction, when the heathen took up their proverb of reproach and asked, Where is now their God? (Psalms 79:10).
