Exodus 34:3
And no man shall come up with thee, neither let any man be seen throughout all the mount; neither let the flocks nor herds feed before that mount. And no man shall come up with thee, neither let any man be seen throughout all the mount; neither let the flocks nor herds feed before that mount.
The command was given for the morning return to the top of Mount Sinai with the two tables of stone Moses had prepared, where the Lord again wrote the words of the covenant, the Ten Commandments, like the first tables. No man was to come up with Moses, no man was to be seen anywhere throughout all the mount, and none were to approach it during his absence, while flocks and herds were barred from feeding before the mount, leaving Moses entirely alone. In that solitude Moses was alone with God on Sinai for forty days and nights, miraculously sustained as during the first forty days.
Complete solitude and separation were required for Moses to meet God and receive the tables. The restriction followed Israel's recent sin and transgression and was imposed because it was dangerous for those who had broken the commandments to be near God's glory. It shows how seriously God regards transgression and His honor for faithfulness and truth.
The exclusion foreshadows that the wicked will be unable to endure the Lawgiver's burning glory when they meet Him over His broken law. The verse calls for entire consecration to God and then proving Him by experience. Professing Christians are to study this chapter to learn to act as Christians and to maintain their connection with God.
