"And take the helmet of salvation, and the sword of the Spirit, which is the word of God" -- Ephesians 6:17
Oh, c'mon, that's one of those concoctions, a little bit from here and a little bit from there to make it sound like it's somewhere in the scripture all in one neat little package. It's obviously biblical engineering;
Let's look at it closely:
"And take the helmet of salvation"from Isa 59:17
"and the sword of the Spirit"Isa 49:2,
and Hos 6:5
(notice how the words of God here don't "save" but kill)
"[the Spirit] which is the word of God"not fund in this context anywhere in the OT (Oh, no, what did the Bereans do!?)and is completely Paul's own construct.
So, what we have here is a collage of two different chapters of Isaiah and one addition made by Paul, neatly packaged as a Biblical statement.
This is like cutting and pasting from various editions of the NY Times the following words Red, Sea, blue, the, not, red, is, but and claiming the NYT says "the Red Sea is red and not blue!"
