God almost killed Moses

Key verses
Matthew 10:29-31 - Are not two sparrows sold for a penny? Yet not one of them will fall to the ground apart from the will of your Father. And even the very hairs of your head are all numbered. So don’t be afraid; you are worth more than many sparrows.

Exodus
It's a good thing that God had a pharaoh come in that didn't know Joseph, or else the Israelites may have stayed there forever in peace with the Egyptians and not shone as a light to all nations.

Exodus 4:24 intrigued me because we just read about God being friendly to Moses, talking to him and giving him a mission to carry out, and then in verse 24, God is about to kill Moses, but Zipporah intervenes.  I read a few commentaries online, and Wesley's notes interested me the most, largely because of the way he phrased his statement regarding the relationship between God and Moses [see bolded part below].
     "It seems the sin of Moses, was neglecting to circumcise his son, which perhaps was the effect of his being unequally yoked with a Midianite, who was too indulgent of her child, and Moses so of her. The Lord met him, and, probably, by a sword in an angel's hand, sought to kill him - This was a great change. Very lately God was conversing with him as a friend, and now coming forth against him as an enemy. In this case of necessity Zipporah herself circumcised the child without delay; whether with passionate words, expressing the dislike of the ordinance itself, or at least the administration of it to so young a child."
