Pride before the fall
Isaiah 10:14. “And my hand hath found as a nest the riches of the people: and as one gathereth eggs that are left, have I gathered all the earth; and there was none that moved the wing, or opened the mouth, or peeped.”
The arrogance of this man is amazing. He brags on himself in the most laudatory terms, likening himself to gathering up the riches of the conquered people like a person would gather eggs from a nest left unprotected by the hen. No one was able to stand against him. He had conquered the whole earth.
Others have made similar claims all down through history, and they have all faded into the dim gray halls of human memory. Most of them will spend all eternity in hell because they trusted in their own power more and ignored Jehovah, the Lord of Hosts.
