Exodus chapter 6 is the beginning of the Lord's promise to Moses to deliver the Israelites from their bondage in Egypt. In this chapter, the Lord reveals Himself to Moses and tells him that He is the God of Abraham, Isaac, and Jacob. He then instructs Moses to go to Pharaoh and demand that he let the Israelites go. The Lord promises to make Pharaoh's heart stubborn so that he will not listen to Moses, but He also promises to bring great plagues upon Egypt if Pharaoh does not comply.
The Lord also reveals His name to Moses in this chapter. He tells Moses that His name is "I AM WHO I AM," which is a powerful statement of His sovereignty and power. He also tells Moses that He is the God of the Hebrews, and that He will bring them out of Egypt with a mighty hand.
The Lord's promise to Moses in this chapter is a powerful reminder of His faithfulness and power. He is the God who keeps His promises, and He will deliver the Israelites from their bondage in Egypt. He is the God who is faithful to His people, and He will bring them out of their captivity with a mighty hand.
