"Now shalt thou see what I will do to Pharaoh"
~ God, Exodus 6:1
BibleGateway: (NIV) (ESV)
SAB (KJV): Chapter5, Chapter6
Blue Letter Bible: Chapter5, Chapter6
tl;dr - Moses is very reluctant to talk with Pharaoh. Pharaoh is very reluctant to give Moses what he wants. We receive the worst-placed genealogy yet. Aaron's going to talk for Moses, and God's goign to be a total dick to make a point.
Moses and Aaron go to talk with Pharaoh and say "Hey, how about you let all the Israelites go worship their God, YHWH, in the desert for three days?" Pharaoh says "Who do you think this "YHWH" of yours is?! Not gonna happen." Moses responds "Oooookay... How about you let all the Israelites go worship their God in the desert for three days ooooorrr, YHWH will come beat the crap out of Egypt?" Pharaoh apparently didn't like Moses/Aaron's tone, because at this point he commanded that all the Hebrews would no longer receive straw to make their bricks (straw was an essential part in making the bricks take a good shape). They had to go get their own straw and keep up on their brick-making quota-- that would keep their minds off this silly "YHWH" business. Of course, this was impossible, so the leaders of the Hebrews were flogged for falling behind schedule. The Hebrew leaders scolded Moses for getting them more work than they already had, which makes Moses feel bad...
Moses goes out to the desert, finds YHWH, and says "Hey, what gives? I did what you said, but it didn't work!" YHWH chuckles and goes "Look, Moses, I'm gonna seriously mess Egypt up. I'm JEHOVA. Not even Abraham and Isaac and Jacob knew my name. I promised all this stuff to the patriarchs, and I'm going to deliver. But first... the Hebrews will know that I AM GOD." Moses goes and tells all the Hebrews the good news that God's going to save them, but the Hebrews were too busy getting flogged for not working enough, and they didn't listen to him. So, with God's encouragement, Moses goes and talks to Pharaoh again. We're not told how that conversation goes. Instead, we're just told that Moses complains to God about his (possible) speech impediment. God charges Moses and Aaron with the responsibility of taking all the Hebrews out of Egypt.
Then there's an accounting of the 12 houses of Israel. Except it winds up only being three of the 12 houses. The author appears to get distracted with Levi's house, since that's where Moses and Aaron come in. Also, both Aaron and Moses (and presumably Miriam, who's stopped showing up for some reason) are the result of a man marrying his father's sister.
After the genealogy is over, we're told again that Moses talks with God about his speech impediment, and God tells him to go talk with Pharaoh.
Ugh, this storytelling! - Chapter 5 wasn't terrible, but Chapter 6 was just horrific! There's plenty of repetition, the genealogy isn't as complete as it says it's going to be, and it's pretty clear that the comments at the end of Chapter 6 are actually part of the story at the beginning of Chapter 7. (Note: the chapters were added quite a bit after these books were first committed to paper, so this just shows how humanity has effected the Bible, not always for the better.) We've got to wonder why God made Shakespeare so much better at writing then Moses (and the other authors of the Bible).
God is doing this so that everyone knows he's God. - God is more than a little bit threatening in here (as if we didn't need to be afraid of him after reading Genesis). Specifically, God has talked about his future actions being to show the Hebrews (and Egyptians) that he is God. So, God's willing to afflict people with boils, send hail to kill cattle, and murder children just to prove the point that he's the baddest guy on the block. But he wouldn't interfere with free will to just make them believe without all the death. Violating free will isn't in his nature (even though he's done it before and will be doing it again soon).

 Blogging the Bible: Exodus 5-6 (I'm actually a little disappointed in this guy-- this is the second time in the book of Exodus that he's missed or forgotten a line that really changes the story. First he said that Moses never was a prince of Egypt [See Exodus 2:10 for why Moses *was*]. Now he's saying that Moses isn't following God's command, because he only asks for three days to go into the wilderness-- but this is exactly what God told Moses to say! [Exodus 3:18])

 Annotated Skeptic's Annotated Bible: That all the earth may know that there is a God in Israel ("It's okay, I just assume that all killed children go to heaven, so God is justified in doing this if it brings their parents to Him. Also, God's the only one who can judge, so HE has to decide if his actions are good. We can't." How can you explain this logic in a way that doesn't show a rotten morality? He's seriously justifying the murder of children for something they never had any control over.)
