For yet a very little while, and the indignation shall cease, and mine anger in their destruction.
For - be not afraid (Isaiah 10:24), For, etc.
Yet a very little while, and the indignation shall cease - the punishments of God against Israel shall be consummated and ended (Isaiah 26:20; Daniel 11:36, "until the indignation be accomplished," etc.)
And mine anger, in their destruction - mine anger shall turn to their (the Assyrians') destruction.
