Exodus 34:1 - Wesley's Explanatory Notes

Moses must prepare for the renewing of the tables. Before God himself provided the tables, and wrote on them; now Moses must hew him out the tables, and God would only write upon them. When God was reconciled to them, he ordered the tables to be renewed, and wrote his law in them, which plainly intimates to us, that even under the gospel (of which the intercession of Moses was typical) the moral law should continue to oblige believers. Though Christ has redeemed us from the curse of the law, yet not from the command of it, but still we are under the law to Christ. When our Saviour in his sermon on the mount expounded the moral law, and vindicated it from the corrupt glosses with which the scribes and Pharisees had broken it, he did in effect renew the tables, and make them like the first; that is, reduce the law to its primitive sense and intention.
