Amos 9:1

"I saw the Lord standing by the altar, and he said: 'Strike the tops of the pillars so that the thresholds shake. Bring them down on the heads of all the people; those who are left I will kill with the sword. Not one will get away, none will escape.'" NIV translation

Amos saw the coming destruction on the pagan temples of the northern kingdom. He saw that it was God who was bringing them down on all who took part in the idolatry. Those that were not killed by the collapsing structures would be killed by the swords of the invading army.

Amos 9:2

"'Though they dig down to the depths below, from there my hand will take them. Though they climb up to the heavens above, from there I will bring them down.'" NIV translation

This verse speaks to the fact that they could not even escape God's judgment by dying. Many people want to believe that they can do anything they want because, after this life, there is nothing else and nobody to answer to. Here, God says that that is not true.

Amos 9:3

"'Though they hide themselves on the top of Carmel, there I will hunt them down and seize them. Though they hide from my eyes at the bottom of the sea, there I will command the serpent to bite them.'" NIV translation

Here, we see that there is no place on the earth where man can hide from God. At the top of Carmel there are caves and men have tried to hide there but God knows where they are and they are still under His control. The same thing (hiding in caves) will be attempted by those who face the Great Tribulation and the result is the same (see Revelation 6:15).
