'Woe' in the Bible

And the Philistines are afraid, for they said, 'God hath come in unto the camp;' and they say, 'Woe to us, for there hath not been like this heretofore.

Woe to us, who doth deliver us out of the hand of these honourable gods? these are the gods who are smiting the Egyptians with every plague in the wilderness.
