On the third new moon after the people of Israel had gone out of the land of Egypt, on that day they came into the wilderness of Sinai.
1. In the third month. This chapter informs us by what means God rendered the people attentive and teachable when He would promulgate His laws. He had, indeed, previously delivered the rule of a just and pious life, but by writing the Law on tables, and by then adding its exposition, He not only embraced the perfect doctrine of piety and righteousness, but ratified it...
God set up His pavilion on a barren mountaintop in the wilderness, not in any city or palace men had built, and thus put contempt upon all our magnificence. The Israelites reckoned on a three days' journey to sacrifice, yet took nearly two months; we are always miscounting the time such things require.
