Exodus 3:19

¹The LORD said to Moses, “Now you shall see what I will do to Pharaoh, for by a strong hand he shall let them go, and by a strong hand he shall drive them out of his land.”

²Pharaoh said, “Who is the LORD, that I should listen to his voice to let Israel go? I don’t know the LORD, and moreover I will not let Israel go.”

¹The LORD said to Moses, “Behold, I have made you as God to Pharaoh; and Aaron your brother shall be your prophet. ²You shall speak all that I command you; and Aaron your brother shall speak to Pharaoh, that he let the children of Israel go out of his land. ³I will harden Pharaoh’s heart, and multiply my signs and my wonders in the land of Egypt. ⁴But Pharaoh will not listen to you, so I will lay my hand on Egypt, and bring out my armies, my people the children of Israel, out of the land of Egypt by great judgments. ⁵The Egyptians shall know that I am the LORD when I stretch out my hand on Egypt, and bring the children of Israel out from among them.”

⁶Moses and Aaron did so. As the LORD commanded them, so they did. ⁷Moses was eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh.

⁸The LORD spoke to Moses and to Aaron, saying, ⁹“When Pharaoh speaks to you, saying, ‘Perform a miracle!’ then you shall tell Aaron, ‘Take your rod, and cast it down before Pharaoh, and it will become a serpent.’”

¹⁰Moses and Aaron went in to Pharaoh, and they did so, as the LORD had commanded. Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent. ¹¹Then Pharaoh also called for the wise men and the sorcerers. They also, the magicians of Egypt, did the same thing with their enchantments. ¹²For they each cast down their rods, and they became serpents; but Aaron’s rod swallowed up their rods. ¹³Pharaoh’s heart was hardened, and he didn’t listen to them, as the LORD had spoken.

¹⁴The LORD said to Moses, “Pharaoh’s heart is stubborn. He refuses to let the people go.

¹¹and brought out Israel from among them, for his loving kindness endures forever; ¹²with a strong hand, and with an outstretched arm, for his loving kindness endures forever;

¹²Who caused his glorious arm to be at Moses’ right hand? Who divided the waters before them, to make himself an everlasting name? ¹³Who led them through the depths, like a horse in the wilderness, so that they didn’t stumble?
