What does Exodus 6:3 mean?
When God spoke to Moses from the burning bush (Exodus 3:4–6), He identified Himself in two ways. One was with the phrase "I am," from the Hebrew eheyeh aser' eheyeh. The other was with the word YHWH, or Yahweh, usually translated as "Lord." The name Yahweh had been used in the biblical text prior to Moses' encounter with God. However, the prima-ry phrase God used to identify Himself had been ēl' saddāy', or El Shad-dai (Genesis 17:1; 35:11), translated as "God Almighty." This was how He presented Himself to Isra-el's patriarchs Abraham, Isaac, and Jacob.Readers will notice that the word YHWH, or "the Lord," has appeared since the earliest pages of the Bible (Genesis 2:4). Since Moses recorded the book of Genesis, this is not surprising. However, there are places in Genesis where "the Lord" is spoken aloud (Genesis 4:1; 13:4; 16:2; 19:13). Scholars suggest one of two explanations:
First is that Moses is using a then-familiar name for God to consistently identify Him. This would be like quoting Sarah saying, "Abraham, God is preventing me from having children," even though her hus-band's name at that moment was actually "Abram" and hers was "Sarai" (Genesis 16:2). Since most people know these persons as "Abraham" and "Sarah," the more common names might be used to avoid misunderstanding. The other possibility is that spoken uses of YHWH in Genesis are literal, and God's meaning here is simply that Yahweh was not His primary self-identification until the time of Mo-ses.
This is part of the Lord's reassurance against Moses' doubts (Exodus 5:22–23). God will continue to explain His history with Israel and His plans to liberate them from Egyptian slavery (Exodus 6:4–6).
