[19:1] 1 sn This chapter is essentially about mediation. The people are getting ready to meet with God, receive the Law from him, and enter into a covenant with him. All of this required mediation and preparation. Through it all, Israel will become God’s unique possession, a kingdom of priests on earth – if they comply with his Law. The chapter can be divided as follows: vv. 1-8 tell how God, Israel’s great deliverer promised to make them a kingdom of priests; this is followed by God’s declaration that Moses would be the mediator (v. 9); vv. 10-22 record instructions for Israel to prepare themselves to worship Yahweh and an account of the manifestation of Yahweh with all the phenomena; and the chapter closes with the mediation of Moses on behalf of the people (vv. 23-25). Having been redeemed from Egypt, the people will now be granted a covenant with God. See also R. E.
