Daniel 3:17

If it be [so], our God whom we serve is able to deliver us from the burning fiery furnace, and he will deliver [us] out of thine hand, O king.

Ver. 17. Our God whom we serve is able to deliver us.] And deliver us he will, either from death or through it; and we are by his grace in utrumque parati, wholly at his disposal. Never ask, then, O king, Who is that God that shall deliver you? Our God is in heaven, and doeth whatsoever he will in heaven and in earth. He well knoweth how to deliver his out of temptations, and to reserve the unjust, be he king or captive, unto the day of judgment to be punished. 2Pe 2:9

From the burning fiery furnace.] Sic fortissimum martyrem, saith Ambrose of Laurentius, may we as well say of these, saevissima persecutoris flarama superare non potuit; quod longe ardentius veritatis radiis accensa mens eius fervebat. The fiery zeal of these men's spirits overcame and put out the most scorching heat of the burning fiery furnace.

And he will deliver us out of thine hand.] Hereof they were well assured, because it would further set forth the cause of God, and work a greater conviction in the king and his nobles.
