What Does Exodus 20:20 Mean?

Moses' pastoral response to the people's terror reframes the theophany's purpose: the terrifying encounter is not punishment but formation. YHWH has come to the community in this overwhelming form "that the fear of him may be before you, that you may not sin." The Sinai encounter is calibrated toward a specific outcome: the lasting reverent awe that prevents covenant violations. The overwhelming experience is not an excess display of divine power but the covenant's most effective formation tool: a one-time encounter so viscerally memorable that its impression shapes the community's obedience for generations.

Moses holds together two apparently contradictory instructions: "do not fear" and "that the fear of him may be before you." The two fears are different in kind. The paralyzing, flight-producing terror that sends the community backing away from the mountain is the fear Moses addresses: do not let this terror govern your future relationship with YHWH. What should govern that relationship is the reverent-awe fear that Proverbs 1:7 calls "the beginning of wisdom": the orientation of the whole person toward YHWH as the defining reality around which all other realities are arranged. Terror produces flight; reverence produces faithfulness.

The new covenant application of the Sinai-fear principle appears throughout the New Testament's worship theology: 1 Peter 1:17 ("conduct yourselves with fear throughout the time of your exile"), Philippians 2:12 ("work out your own salvation with fear and trembling"), Hebrews 12:28 ("let us offer to God acceptable worship, with reverence and awe").

The Sinai formation-by-overwhelming-encounter produces the fear that the apostles consistently call the new covenant community to maintain: not the enslaving fear of illegitimate authority but the worshipful reverence of those who have encountered the consuming fire and been neither destroyed nor abandoned.
