'Collapse' in the Bible

So this sin will become your downfall. You will be like a high wall that bulges and cracks and is ready to collapse; it crumbles suddenly, in a flash.

On every high mountain and every high hill there will be streams flowing with water, at the time of great slaughter when the fortified towers collapse.

Because of the long distance you must travel, you get tired, but you do not say, 'I give up.' You get renewed energy, so you don't collapse.
