The Lord said to Moses, “Go to Pharaoh, for I have hardened his heart and the heart of his servants, in order to display these signs of mine before him,
Go to Pharaoh in the morning when he goes out to the water. Position yourself to meet him by the edge of the Nile, and take in your hand the staff that was turned into a snake.
Pharaoh sent representatives to investigate, and indeed, not even one of the livestock of Israel had died. But Pharaoh’s heart remained hard, and he did not release the people.
Indeed, they made their heart as hard as diamond, so that they could not obey the Torah and the other words the Lord who rules over all had sent by his Spirit through the former prophets. Therefore, the Lord who rules over all had poured out great wrath.
But King Sihon of Heshbon was unwilling to allow us to pass near him because the Lord our God had made him obstinate and stubborn so that he might deliver him over to you this very day.
Take care not to refuse the one who is speaking! For if they did not escape when they refused the one who warned them on earth, how much less shall we, if we reject the one who warns from heaven?
