'Disappointed' in the Bible

Why do you go about changing your mind so much? You will also be disappointed by Egypt, just as you were disappointed by Assyria.

They have sown wheat, but they have harvested thorns. They have tired themselves out, but they don't show a profit. Now be disappointed about your harvest because of the fierce anger of the LORD.

Their nobles send their young people for water. They go to the cisterns, but they find no water. They return with their vessels empty. They're disappointed and dismayed, and they cover their heads in shame.

The ground is cracked, because there has been no rain in the land. The farmers are disappointed, and they cover their heads in shame.
