Job famously remarked after losing his family and most of his possessions, "the Lord gave, and the Lord has taken away." (Job 1:21) While this statement is certainly correct, it doesn't explain why. In this passage we see a similar situation, but with a bit more detail which may provide an answer. An expository sermon from Isaiah 3-4; sermon begins at about 26:20.

No one escapes from God's eyes and justice. He will do what He promises.
