'Able to Deliver' in the Bible

If it is, our God whom we served will be able to deliver us from the furnace of flaming fire, and from thy hand, O king, he will deliver us.

{ And an edict being set from me, That every people, nation and tongue, that shall say an error against their God, of Shadrach, Meshach, and AbedNego, shall be made pieces, and his house shall be set a dung-hill, because that there is no other God that shall be able to deliver according to this.}
