'Wonder' in the Bible

And the LORD said, Like as my servant Isaiah hath walked naked and barefoot three years for a sign and wonder upon Egypt and upon Ethiopia;

Stay yourselves, and wonder; cry ye out, and cry: they are drunken, but not with wine; they stagger, but not with strong drink.

Therefore, behold, I will proceed to do a marvellous work among this people, even a marvellous work and a wonder: for the wisdom of their wise men shall perish, and the understanding of their prudent men shall be hid.
