Ex 6:3

6:3 God Almighty. God had revealed Himself to the patriarchs as God Almighty (Hebrew El Shaddai, Gen. 17:1; 28:3; 35:11). In Genesis, however, the name Yahweh is much more commonly used, perhaps only to identify the God of the fathers as Yahweh, the Lord. Nevertheless, while some passages seem to imply the use of Yahweh from the earliest time (Gen. 4:26; 9:26; 12:8; 24:12), it is not found as an element in personal names (Ja- or Jo) before the time of Moses, with the possible exception of Jochebed (6:20). In any case, God identifies Himself as El Shaddai, the God of the patriarchs, but reveals Himself afresh as Yahweh, the covenant God who claims and redeems Israel according to His gracious purpose.
