Ezekiel chapter 5

vs 10

People eating people is generally a mark of a siege gone bad. Food has run out, and there's nothing else to eat. Then, once they are broken anyway, they are scattered, exiled. Interesting thing for God to say, though, that he's never done it before. I guess he's never done it to Jerusalem before - although it probably did happen

vs 11

I'm guessing that the 'shave' refers to the shaving Ezekiel did with the sword, and so God is going to 'shave' his people the same way, treat them the way that hair was treated.

vs 12

Because, see, this matches exactly what was done to the hairs. Ezekiel isn't just making this stuff up. God isn't just making idle threats. And the people who have already left Jerusalem are seeing that it's not really time to return yet, because it's getting worse.

vs 13

God knows that sometimes actions speak louder than words. So he 'has spoken' when his wrath has finally subsided and almost everyone is dead. A lot of people are going to die because God is really angry. He doesn't screw around.

vs 14

See, Ezekiel is already getting a taste of what it's like to be an object lesson - like "lie on your side for 390 days and eat bread cooked on poo". So now imagine, "have a good two thirds of your people killed and the others chased over the countryside with a sword, so people know I don't screw around."

vs 15

"You're such an Israel" doesn't really work, but "Don't mess with that God, he kills his own men" a la Mystery Men does apply.

vs 16

God is not messing around, he is making this clear. He is going to shoot to kill. With arrows of famine. Which, forgive me, sounds like a D&D magic item if ever I heard of one.

vs 17

This is all repeated from the curses God promised in Leviticus and Deuteronomy. It isn't new, in that way. But it is pretty shocking when you stop reading them as "This I will do if it ever comes to that", and start reading them as, "These are imminent, you are going to suffer really, really badly." Yes, I will admit that if I were an Israelite back in the promised land days, I wouldn't have taken those curses seriously when I first heard Moses speaking them.
