After the firstborn of Egypt died, what did Pharaoh tell Moses and Aaron that night?

Answer: Get up and leave my people

Pharaoh summoned them by night: "Get up, leave my people... Take your flocks and herds as well... and depart! And bless me also."

“Then Pharaoh summoned Moses and Aaron by night and said, “Get up, leave my people, both you and the Israelites! Go, worship the LORD as you have requested. Take your flocks and herds as well, just as you have said, and depart! And bless me also.””— Exodus 12:31-32 (BSB)
