God replied, “I will be with you. And you will know that I am the one who sent you, when you worship me on this mountain after you have led my people out of Egypt.”
The leaders of Israel will listen to you. Then you must take them to the king of Egypt and say, “The LORD God of the Hebrews has appeared to us. Let us walk three days into the desert, where we can offer a sacrifice to him.”
Moses and Aaron went to the king of Egypt and told him, “The LORD God says, ‘Let my people go into the desert, so they can honour me with a celebration there.’ ”
They answered, “The LORD God of the Hebrews, has appeared to us. Please let us walk three days into the desert where we can offer sacrifices to him. If you don't, he may strike us down with terrible troubles or with war.”
