Exodus 3:13; Exodus 3:18

13 Moses said to God, “Suppose I go to the Israelites and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ Then what shall I tell them?”

18 “The elders of Israel will listen to you. Then you and the elders are to go to the king of Egypt and say to him, ‘The LORD, the God of the Hebrews, has met with us. Let us take a three-day journey into the wilderness to offer sacrifices to the LORD our God.’
