'Holy One of Israel' in the Bible

“Call together many [archers] against Babylon,All those who bend the bow.Encamp against her on every side;Let no one from there escape.Repay her according to her actions;Just as she has done, do to her.For she has been proudly defiant and presumptuous against the Lord,Against the Holy One of Israel.

For neither Israel nor Judah has been abandonedBy his God, the Lord of hosts,Though their land is full of sin and guiltBefore the Holy One of Israel.
