The eternal God is your refuge, and underneath are the everlasting arms: and he shall thrust out the enemy from before you; and shall say,
Destroy them.

Hebrew, "The eternal God is thy refuge; or, From eternity is the abode of God, or in fine, the protection of the Lord is before, and his eternal arms underneath "so that nothing can hurt you. (Calmet)
