What four tasks did God promise his people he would accomplish?

Answer 1

The covenant between God and the Israelite nation (see Exodus ch.19 and ch.24), was made in the time of Moses, with Moses serving as the messenger.
This covenant is one of obedience, to listen to God's voice (Exodus 19:5), which will include the entire Torah (24:12). God, for His part, promised to treasure the Israelites (Exodus 19:5, Deuteronomy 26:16-19). The covenant was manifested through God's giving the Ten Commandments (Exodus ch.19-20), and was finalized (on our part) through the offerings described in Exodus ch.24. God promised:
1) To give the Israelites the land of milk and honey (the Promised Land). Exodus ch.3.
2) To redeem them from the Egyptian slavery and smite the Egyptians (Exodus ch. 3-4; see also Genesis ch.15).
3) To give them the wealth of Egypt (Genesis ch.15; Exodus ch.3).
4) To give them the Torah (Exodus 24:12).
5) To cherish them as a treasure (Exodus ch.19; Deuteronomy 26:16-19).
6) To drive the Canaanites out of the Promised Land (Exodus ch.23).
7) To do unparalleled miracles for them (Exodus ch.34).
8) To dwell among them (Exodus ch.25).
9) To give them large families, wine and oil, and livestock (Deuteronomy ch.7).
10) To give them prophets (Deuteronomy ch.18).
11) To return His presence and blessings to them in the end of days (Deuteronomy ch.30).See also:
