13 YHWH said to Moses, “Rise up early in the morning, and stand before Pharaoh, and tell him, ‘This is what YHWH, the God of the Hebrews, says: “Let my people go, that they may serve me. 14 For this time I will send all my plagues against your heart, against your officials, and against your people; that you may know that there is no one like me in all the earth. 15 For now I would have stretched out my hand, and struck you and your people with pestilence, and you would have been cut off from the earth; 16 but indeed for this cause I have made you stand: to show you my power, and that my name may be declared throughout all the earth, 17 because you still exalt yourself against my people, that you won’t let them go. 18 Behold, tomorrow about this time I will cause it to rain a very grievous hail, such as has not been in Egypt since the day it was founded even until now. 19 Now therefore command that all of your livestock and all that you have in the field be brought into shelter. The hail will come down on every man and animal that is found in the field, and isn’t brought home, and they will die.”’” Exodus 9:13-19WEB
This passage contains a positive command, directed toward Pharaoh, through Moses: 'Go and tell Pharaoh to let my people go".
The command is followed by an explanation of God's purpose for them, "that they may serve me", and of the penalty which God intends to impose on a disobedient Pharaoh.
It is relevant to an understanding of Stewardship, because it relates to Pharaoh's stewardship over God's possession Israel. It is relevant to an understanding of Prophecy because Moses is acting as prophet of God, relaying a direct revelation from God to Pharaoh.
The command to Moses and Aaron was fulfilled by them when they obeyed God and delivered his message to Pharaoh. The command to Pharaoh was later fulfilled by a begrudging Pharaoh in the face of God's mighty hand of judgement.
