Exodus 3:19-21

New International Version - UK

¹⁹ But I know that the king of Egypt will not let you go unless a mighty hand compels him. ²⁰ So I will stretch out my hand and strike the Egyptians with all the wonders that I will perform among them. After that, he will let you go.

²¹ ‘And I will make the Egyptians favourably disposed towards this people, so that when you leave you will not go empty-handed.
