6:18

says Jehovah, the Almighty: The statements Paul quotes in this verse are apparently taken from 2Sa 7:14 and Isa 43:6. The phrase “says Jehovah, the Almighty,” seems to be quoted from the Septuagint version of 2Sa 7:8, where the original Hebrew text reads: “This is what Jehovah of armies says.” With quotes from the Hebrew Scriptures, Paul urges Christians to avoid false worship and the use of lifeless, powerless idols. By doing so, they can qualify as “sons and daughters” of “Jehovah, the Almighty.”​—See App. C1 and C2.

the Almighty: The Greek word Pan·to·kraʹtor, here rendered “the Almighty,” could also be translated “the Ruler Over All; the One Who Has All Power.” In this context, Paul urges Christians to avoid false worship and the use of lifeless, powerless idols (2Co 6:16) in order to qualify as children of “the Almighty.” In the Christian Greek Scriptures, this is the first of ten occurrences of the term rendered “the Almighty.” The other nine are found in the book of Revelation.​—Re 1:8; 4:8; 11:17; 15:3; 16:7, 14; 19:6, 15; 21:22.
