The purpose of God’s calling of Moses was, negatively, to deliver the children of Israel out of the usurpation and tyranny of Pharaoh and Egypt, and, positively, to bring them into Canaan, the land flowing with milk and honey (Deut. 8:7-9), where they could establish God’s kingdom (Exo. 19:6; 2 Sam. 5:12; 7:12, 16) and build up His dwelling place on earth (2 Sam. 7:13). In typology, this signifies delivering people out of the usurpation and tyranny of Satan and the world, and bringing people into Christ, the all-inclusive One typified by the land of Canaan (see note Deut. 8:71), for the building up of the church as God’s kingdom and God’s dwelling place on earth (Rom. 14:17; Eph. 2:20-22; 4:12).
As revealed in this chapter, in fulfilling God’s purpose the children of Israel passed through three stations: the wilderness (v. 18), the mountain (v. 12), and the good land (vv. 8, 17). By the passover (Exo. 12:11, 31-41) and the crossing of the Red Sea (Exo. 14:21-30) the children of Israel came out of Egypt and into the wilderness. Then, they were brought to the mountain by means of the tree which made the bitter waters sweet (Exo. 15:23-25), by means of the twelve springs at Elim (Exo. 15:27), by means of the manna from heaven (Exo. 16:14-15, 31-32, 35), by means of the living water from the cleft rock (Exo. 17:6), and by means of the victory over Amalek (Exo. 17:8-16). At the mountain they received a revelation of what God is, of the life they should live according to God’s attributes, and of the desire of God’s heart to have a dwelling place on earth among His people (chs. 19—34). They also built the tabernacle as God’s temporary dwelling place on earth (chs. 35—40). Finally, by the Ark with the tabernacle the children of Israel entered into the good land (Josh. 3:3, 6, 8, 13-17; 4:10-19). There, through the enjoyment of the rich produce of the land, they defeated the Canaanites, who occupied the land, and built the temple as God’s permanent dwelling on earth (1 Kings 6). Such a history of the children of Israel is a portrait of a believer’s full salvation.
