2 Corinthians 6:18 - Ellicott's Commentary On The Whole Bible

And will be a Father unto you... — Again we have, as it were, a mosaic of citations: “I will be a Father....” from 2 Samuel 7:14; “Sons and daughters” from Isaiah 43:6; “Saith the Lord Almighty” from the Greek of 2 Samuel 7:8. It may be noted as not without interest that the Greek word rendered “Almighty” here, and “Omnipotent” in Revelation 19:6, is commonly used in the LXX. as an equivalent for the Hebrew “Lord of Hosts” or “Lord of Sabaoth.”
