Bible References: Rev. 4:8; 11:17; 15:3; 16:7; 19:6 (the word omnipotent appears in the KJV); 21:22
The four living creatures, each one of them having six wings, are full of eyes around and within; and day and night they do not cease to say,
Holy, holy, holy is the Lord God, the Almighty, who was and who is and who is to come.” (Revelation 4:8)
Tseva’ot is used of various activities than require dedication and regimentation of life. For instance, service in the tabernacle (Ex. 38:8; Num. 4:23, 35, 39, 43; 8:24) and service in war (Num. 31:14). It is used of God’s celestial host (Gen. 2:1; Pss. 33:6; 103:21; Isa. 40:26). Israel are also called the “hosts of the Lord” (Ex. 12:41).
The words “Holy, holy, holy, Lord God Almighty are from Isaiah 6:3 combined with other Old Testament verses, but the name of God in Isaiah is Lord of hosts (Yahweh tseva’ot). The reason for the change is that in some places in the Greek Old Testament, the word pantokratōr was used to translate the name Lord of hosts (Jer. 5:14; Amos 4:13). Pantokratōr means “all-powerful.” “Almighty” is a good translation of pantokratōr. However, while the Hebrew word places the emphasis on the resources available to God, the Greek emphasizes His might.
Where the title Lord God Almighty is found in the New Testament it is really a combined quotation of Isaiah 6:3, Jeremiah 5:14, and Amos 4:13, which refer to God as Lord of hosts or Lord God of hosts.
One similar Old Testament name of God is Yahweh tseva’ot, which is translated in different ways: Lord Almighty (NIV) or LORD of hosts (NASB). Another similar name is God Almighty (’El shaddai). In the New Testament the name Lord Almighty occurs in the NIV of Rom. 9:29; Jas. 5:4 (Kyrios sabaōth) and in 2 Cor. 6:18 (Kyrios pantokratōr).
