17 This is what Jehovah says: “By this you will know that I am Jehovah.+ Here I am striking the water that is in the Nile River with the rod that is in my hand, and it will turn into blood.

9 Then Moses said to Pharʹaoh: “I leave to you the honor of telling me when I should plead to have the frogs removed from you, your servants, your people, and your houses. Only in the Nile River will they be left.” 10 To this he said: “Tomorrow.” So he said: “It will be according to your word so that you may know that there is no one else like Jehovah our God.+

22 On that day I will certainly set apart the land of Goʹshen, where my people are dwelling. No gadflies will exist there,+ and by this you will know that I, Jehovah, am here in the land.+

29 So Moses said to him: “As soon as I go out of the city, I will spread out my hands before Jehovah. The thunder will stop and the hail will not continue any longer, so that you may know that the earth belongs to Jehovah.+

4 I will allow Pharʹaoh’s heart to become obstinate,+ and he will chase after them, and I will glorify myself by means of Pharʹaoh and all his army;+ and the Egyptians will certainly know that I am Jehovah.”+ So that is what they did.
