New Defender's Study Bible Notes
3:25 the Son of God. God is, indeed, able to “deliver us” (Daniel 3:17), sending “a son of God” (literal reading), one of His mighty angels, to defend and protect His children, if He so wills (note Psalm 34:7). This has often happened, even when they were not aware of his presence. In this special case, this Son of God may even have been the Angel of the Lord, the pre-incarnate Christ.
