Quick notes on Exodus
Humans forget; Egypt forgets what it owes Israel. Yet Israel has not forgotten the Lord so much that they do not cry out to Him for help, and the Lord has not forgotten Israel: the midwives feared Him, and acted out of holy fear; the Lord has been with Israel the whole time, making them increase in number “so that the land was filled with them” (ESV).
Moses’ early biography is done in the same broad strokes as used later for Jesus: primary events are mentioned, but years and even decades are left unmentioned because they do not bear on the events/actions/focus at hand.
Does Moses face in Pharaoh his brother, cousin, or nephew by adoption?
Unpleasant critters and skin conditions abound.
The distance between the people of Israel and Pharaoh is not great; even foremen from amongst the slaves can visit him, even Moses can wander into court — he’s king, but his court breathes.
There is little to no hint of rebellion against Pharaoh by the Egyptians, even after they were pummeled with a few plagues. He speaks for Egypt, just as Moses speaks for the Lord.
The necessity of the blood on the doorposts for the safety of the firstborn of Israel (Ex 12), the application of the blood of the covenant on the people (Ex 24), as well as the establishment of a border around the holy mountain for the protection of individual Israelites (and even their animals; see esp. Ex 19.10–14, 21–25), shows just how frightful the God of Israel is in His holiness for those who are not holy, for those who have not been cleansed with the blood of the lamb.
Moses has learned patience in his years of watching sheep.
Design is at least as important as the particular laws given to Israel in Exodus.
God will not tolerate idols, even an idol which is supposedly of Him (esp. Ex 32.1, 4–5. Notice how in this first major bout of idolatry by Israel, the One God is possibly (let us stress possibly; most translations I have examined in this case translate אֱלֹהִים in the plural; it seems to me that the singular is more likely) multiplied at once into at least two gods (Ex 32.1, עֲשֵׂה־לָנוּ אֱלֹהִים, “make for us gods”; Ex 32.4, אֵלֶּה אֱלֹהֶיךָ, “these gods”; these are in line with the LXX), even though there is but one calf).
God is with His people as they go through the desert; they see His presence, they see His acts, they have been rescued from slavery, they have His Law, and still how little any of those things matter or make a difference in their words or deeds.
