'Cannot' in the Bible

"No one can serve two masters, because either he will hate one and love the other, or be loyal to one and despise the other. You cannot serve God and riches!"

A good tree cannot produce bad fruit, and a rotten tree cannot produce good fruit.

He went away a second time and prayed, "My Father, if this cup cannot go away unless I drink it, let your will be done."
