Chapters 1-3

Exodus 1:12 - "The more they afflicted them, the more they multiplied..." Just like persecuting the church only makes it grow more.

Exodus 2:9 - "I shall give you your wages." Moses' mother (not even named) gave the child up into God's hands. The Lord put the child back into her hands with wages! She received back even more than she gave up, for she received wages for what she would have done in the first place, i.e., nurse her child. That is just how the Lord works sometimes. Other times, we have to wait for heaven to receive our reward.

Exodus 2:15ff - The Midianites were descendants of Abraham by his second wife, Keturah, whom he married after Sarah died (Gen 25:1-2). Thus, Zipporah was technically a part of Abraham's family. But, Moses still "sent her away" (i.e., divorced her) later in the wilderness wandering (Ex 18:2), presumably because she while she was out of the loins of Abraham, she was still not an Israelite. On account of the fact that she was not born from Israel, i.e., Jacob before his name was changed by the Lord to Israel.

Exodus 2:23 - Many think that the Hebrews cried out to the Lord, but they did not. Read the text for what is actually written, "they sighed because of the bondage" and "their cry for help...rose up to God." Where is it written that they cried out to God? No where. It is as if they hit their thumb with a hammer, cried out, "OUCH!" And the Lord heard their cry. (See also vs. 24.)

Exodus 3:8 - "I have come down to deliver them..." If I were Moses, and I had no prior knowledge of the Lord, I might ask the question, "Can this 'god' (For he did not know all we know. He thought the Lord was just another 'god') defeat the Egyptian gods?" The burning bush that was not consumed was a small display of the Lord's power to Moses. This may answer the question, "Why did the Lord use the burning bush in the first place? Couldn't He have just spoken to Moses with the same effect?"

Exodus 3:11 - This question Moses asks I do not think has to be one of humility, as in "I am just a shepherd. Why would you choose me to do this great work?" I think this was a question of ability. Moses clearly saw himself as powerless to come against Pharaoh. Thus in the next verse, the Lord assures Moses that He will be with him lending power to Moses, as that phrase came to mean later in the Scriptures (see Judges 6:16 and Isaiah 43:2). Later in the chapter, the Lord tells Moses that He will do wonders and miracles to bring them out, once again assuring Moses of His intentions.

Exodus 3:15 - What an awesome moment that must have been when the Lord said His name for the first time. In the English text, the force is diminished because we render the divine name as "LORD." But to see the Hebrew letters forming the divine name is striking.
One other point: In the Hebrew text, there is not a heavy accent on the divine name, which would be there if the Lord wanted to draw extra attention to His name and separate it from the rest of the sentence. It is a very light disjunctive accent, which means after the Lord said His divine name, He was still not finished describing Himself. It should all be read together, "The LORD, the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob..." This defines the Lord more completely and thoroughly so there is no mistaking His identity. He is the LORD!
