Matthew 5:1-20 retells the Beatitudes, which form the beginning of the Sermon on the Mount. Then Jesus added the spiritual dimension to the Mosaic Law. He had not come to destroy the Law, but to fulfill it.
In Exodus 33 God told the Israelites to leave the place they were staying, take off all the ornaments they were wearing and go to the promised land. Moses established the tent of meeting, and there he asked to see God. God promised Moses he would see His back while hiding “In the cleft of the rock”
After breaking the two stone tablets, Moses in Exodus 34 had to go back up the mountain and write the words of God on two new stone tablets. Then God repeated much of what was said in previous chapters, even reiterating the Covenant, but the chapter ends with the radiant face of Moses because Moses had spoken with God.
