'Flesh' in the Bible

This is what the Lord says:The man who trusts in mankind,who makes human flesh his strengthand turns his heart from the Lord is cursed.

I will make them eat the flesh of their sons and their daughters, and they will eat each other’s flesh in the siege and distress that their enemies, those who want to take their life, inflict on them.

The tumult reaches to the ends of the earthbecause the Lord brings a case against the nations.He enters into judgment with all flesh.As for the wicked, He hands them over to the sword—this is the Lord’s declaration.

“Look, I am Yahweh, the God of all flesh. Is anything too difficult for Me?
