13 Then the Lord said to Moses, “Get up early in the morning and present yourself to Pharaoh. Tell him: This is what Yahweh, the God of the Hebrews says: Let My people go, so that they may worship Me.
14 Otherwise, I am going to send all My plagues against you, your officials, and your people. Then you will know there is no one like Me in all the earth.
15 By now I could have stretched out My hand and struck you and your people with a plague, and you would have been obliterated from the earth.
16 However, I have let you live for this purpose: to show you My power and to make My name known in all the earth.
17 You are still acting arrogantly against My people by not letting them go.
18 Tomorrow at this time I will rain down the worst hail that has ever occurred in Egypt from the day it was founded until now.
19 Therefore give orders to bring your livestock and all that you have in the field into shelters. Every person and animal that is in the field and not brought inside will die when the hail falls on them.”
