He said, “But I will be with you, and this shall be the sign for you, that I have sent you: when you have brought the people out of Egypt, you shall serve God on this mountain.”
English Standard Version (ESV)
The promise of serving God on this mountain isn't just a future reward; it's a sign now that God's presence ensures Moses' success. This means the completion of the mission is already a certainty in God's mind, offering Moses a profound assurance for the daunting task ahead.
He said, “But I will be with you, and this shall be the sign for you, that I have sent you: when you have brought the people out of Egypt, you shall serve God on this mountain.”
English Standard Version (ESV)
Moses, hesitant after God calls him to lead the Israelites out of Egypt, expresses his doubts about his own ability and the people's potential rejection. God responds by assuring Moses of His presence and providing a future sign: that the people will worship Him on this very mountain after their liberation from slavery. This promise, though seemingly distant, serves as a confirmation that God's power will ensure their deliverance and bring them to this designated place.
Moses felt inadequate, facing Pharaoh and a stubborn people. What did God offer as the ultimate reassurance? It wasn't a magic wand, but something far more profound.
More Than Just a Promise
Moses had just expressed his doubts about his ability to lead the Israelites out of Egypt. He was aware of his own limitations. God's response, 'Certainly I will be with you,' wasn't just a passive statement; it was an active, powerful declaration of His intent to be present and engaged in the mission. This presence is presented as the primary assurance, more significant than any tangible sign.
God gives Moses a 'sign' to confirm His sending. But it's not a sign that happens right away. What does this future event signify, and why is it given now?
