the LORD had done to Pharaoh and the Egyptians for Israel's sake
and about all the hardships they had met along the way
the LORD had done for Israel
Moses had been invited to stay with Jethro and had eventually married Jethro's daughter Zipporah. Moses had continued to care for Jethro's flocks until the LORD spoke to Moses from a burning bush and sent him back to Egypt to rescue the enslaved Israelites. Moses had taken his wife and two sons with him when he left for Egypt.
