This chapter is really short, it’s just God declaring what will happen next. In chapter 12 he will give instructions for the first Passover, the firstborn in all of Egypt will die, the Hebrews will be driven out, and God will institute the annual Passover feast. That chapter is not short.

Exodus 11

The Lord said to Moses “I will bring one plague more on Pharaoh, and on Egypt; afterwards he will let you go from here: and when he lets you go he will surely drive you out from here.
