34:1-4 When God made man in his own image, the moral law was written in his heart, by the finger of God, without outward means. But since the covenant then made with man was broken, the Lord has used the ministry of men, both in writing the law in the Scriptures, and in writing it in the heart. When God was reconciled to the Israelites, he ordered the tables to be renewed, and wrote his law in them. Even under the gospel of peace by Christ, the moral law continues to bind believers. Though Christ has redeemed us from the curse of the law, yet not from the commands of it. The first and the best evidence of the pardon of sin, and peace with God, is the writing the law in the heart.

4. Moses … took in his hand the two tables of stone—As Moses had no attendant to divide the labor of carrying them, it is evident that they must have been light, and of no great dimensions—probably flat slabs of shale or slate, such as abound in the mountainous region of Horeb. An additional proof of their comparatively small size appears in the circumstance of their being deposited in the ark of the most holy place (Ex 25:10).
