'Cannot' in the Bible

Yet the number of the sons of IsraelShall be like the sand of the sea,Which cannot be measured or numbered;And in the placeWhere it is said to them,“You are not My people,”It will be said to them,“You are the sons of the living God.”

When Ephraim saw his sickness,And Judah his wound,Then Ephraim went to Assyria [instead of the Lord]And sent to [Assyria’s] great King Jareb [for help].But he cannot heal youNor will he cure you of your wound [received in judgment].
