Adam Clarke on Isaiah 25:8

He will swallow up death - He, by the grace of God, will taste death for every man. Heb 2:9. Probably, swallow up death, and taste death, in both these verses, refer to the same thing: Jesus dying instead of a guilty world. These forms of speech may refer to the punishment of certain criminals; they were obliged to drink a cup of poison. That cup which every criminal in the world must have drunk, Jesus Christ drank for them; and thus he swallowed up death: but as he rose again from the dead, complete victory was gained.

From these three verses we learn: -

I. That the Gospel is a plenteous provision: "I will make a feast for all people."

II. That it is a source of light and salvation: "I will destroy the veil. I will abolish death. and bring life and immortality to light."

III. That it is a source of comfort and happiness: "I will wipe away all tears from off all faces."

As in the Arabic countries a covering was put over the face of him who was condemned to suffer death, it is probable that the words in Isa 25:7 may refer to this. The whole world was condemned to death, and about to be led out to execution, when the gracious Lord interposed, and, by a glorious sacrifice, procured a general pardon.
