The contrast between the covering cloud that embraced Moses (v. 18) in blessed fellowship and communion with His Maker and the “devouring fire” is significant. Those who, like Moses, walk in God’s ways may be assured of protection and security “in the secret place ... under the shadow of the Almighty” (Ps. 91:1, 2). Those who turn from the paths of righteousness will find, not comfort and assurance, but retributive justice, for God will appear to them as “consuming fire” (Heb. 12:25, 29).
