12 Moreover, the Lord hardened the heart of Pharaoh, so that he did not listen to them, just as the Lord had spoken to Moses.
13 Then the Lord said to Moses, “Rise up early in the morning, and stand before Pharaoh, and say to him, ‘Thus says the Lord, the God of the Hebrews: Let My people go, so that they may serve Me.
14 For I will at this time send all My plagues upon you and your servants and your people, so that you may know that there is none like Me in all the earth.
15 For by now I could have stretched out My hand, so that I might strike you and your people with pestilence, and you would be cut off from the earth.
16 But, indeed, for this cause I have raised you up, in order to show in you My power and so that My name may be declared throughout all the earth.
17 Still, you exalt yourself against My people by forbidding them to go.
18 Certainly, tomorrow about this time I will cause it to rain a very severe hail, such as has not happened in Egypt since it was founded until now.
