John Trapp on Isaiah 8:13

Ver. 13. Sanctify the Lord of hoſtes himſelf] Even your ſweeteſt Immanuel: non ſanctificatur autem niſi in eum credatur; ſanctify him, I ſay, by believing in your hearts and confeſſing with your mouths, Rom. 10.9. and walking as becommeth the Goſpel,—in nothing terrified by your adverſaries, Phil. 1.27, 28.

And let him be your fear] That is, the Object of your fear, as Gen. 31.53. Pſal. 76.11. where God is called Fear by an Appellative Proper. So the Chaldee Paraphraſe frequently calleth God Dechilah, 1. Fear. The Greeks call him [non-Latin text not transcribed] of [non-Latin text not transcribed] Fear. Bernard ſaith well, God is to be feared as a Lord, honoured as a Father, loved as a Spouſe. This fear of God is a ſoveraign remedy againſt the fear of the creature; and is therefore here and elſwhere oppoſed to it. Surely as one fire driveth out another: and as Moſes his Serpent ſwallowed up the Sorcerers Serpents: ſo here.
