Exodus 9: 1-7
Then the LORD said to Moses, Go in to Pharaoh, and tell him, Thus said the LORD God of the Hebrews, Let my people go, that they may serve me. For if you refuse to let them go, and will hold them still, Behold, the hand of the LORD is on your cattle which is in the field, on the horses, on the asses, on the camels, on the oxen, and on the sheep: there shall be a very grievous murrain. And the LORD shall sever between the cattle of Israel and the cattle of Egypt: and there shall nothing die of all that is the children’s of Israel. And the LORD appointed a set time, saying, To morrow the LORD shall do this thing in the land. And the LORD did that thing on the morrow, and all the cattle of Egypt died: but of the cattle of the children of Israel died not one. And Pharaoh sent, and, behold, there was not one of the cattle of the Israelites dead. And the heart of Pharaoh was hardened, and he did not let the people go.
Egyptian Pharaoh hardened his heart, trying every possible means to hinder the Israelites from leaving Egypt. However, God’s authority is supreme; He sent down ten plagues on Egypt and led the Israelites to cross the Red Sea safely by miracles, to enter the good land of Canaan in the end. It can be seen that no one can hinder the thing God wishes to accomplish.
