'Wonders' in the Bible

See, I and the children whom the Lord has given me, are for signs and for wonders in Israel from the Lord of armies, whose resting-place is in Mount Zion.

This comes from the Lord of armies, purposing wonders, and wise in all his acts.

But these two things will come on you suddenly in one day, the loss of children and of husband: in full measure they will come on you, for all your secret arts, and all your wonders.
