Exodus 11

In the presence of Pharaoh, Moses communicates the message form God. The next plague will compel Pharaoh to let the Israelites go. The firstborn of every Egyptian family and animal will perish.

Moses instructs the Israelites to borrow gold and silver from the Egyptians.
Then Moses angrily left Pharoah.

Moses and Aaron are greatly respected throughout the land by both Egyptian and Israelites. Neither octogenarians are employed, possessors of any special skills or great wealth.
