Exodus 7:13 Yet Pharaoh’s heart became hard and he would not listen to them, just as the LORD had said.

Exodus 4:1-5 Moses answered, “What if they do not believe me or listen to me and say, ‘The LORD did not appear to you’?”
2 Then the LORD said to him, “What is that in your hand?”
“A staff,” he replied.
3 The LORD said, “Throw it on the ground.”
Moses threw it on the ground and it became a snake, and he ran from it. 4 Then the LORD said to him, “Reach out your hand and take it by the tail.” So Moses reached out and took hold of the snake and it turned back into a staff in his hand. 5 “This,” said the LORD, “is so that they may believe that the LORD, the God of their fathers—the God of Abraham, the God of Isaac and the God of Jacob—has appeared to you.”

Exodus 3:11, 12 But Moses said to God, “Who am I that I should go to Pharaoh and bring the Israelites out of Egypt?”
12 And God said, “I will be with you. And this will be the sign to you that it is I who have sent you: When you have brought the people out of Egypt, you will worship God on this mountain.

Genesis 50:18-21 His brothers then came and threw themselves down before him. “We are your slaves,” they said.
19 But Joseph said to them, “Don’t be afraid. Am I in the place of God? 20 You intended to harm me, but God intended it for good to accomplish what is now being done, the saving of many lives. 21 So then, don’t be afraid. I will provide for you and your children.” And he reassured them and spoke kindly to them.

Genesis 47:7-10 Then Joseph brought his father Jacob in and presented him before Pharaoh. After Jacob blessed Pharaoh, 8 Pharaoh asked him, “How old are you?”
9 And Jacob said to Pharaoh, “The years of my pilgrimage are a hundred and thirty. My years have been few and difficult, and they do not equal the years of the pilgrimage of my fathers.” 10 Then Jacob blessed Pharaoh and went out from his presence.
