When verse 5 recently struck me, I guess for the first time (although I have read it several times in the past) it struck hard. The Holy Spirit (which is apparently the spirit referred to) is jealous? I checked some other versions of the Bible:
5 Do ye think that the scripture saith in vain, The spirit that dwelleth in us lusteth to envy? (KJV)
5 Or do you think Scripture says without reason that the spirit he caused to live in us envies intensely?
Text note: Or that God jealously longs for the spirit that he made to live in us; or that the Spirit he caused to live in us longs jealously (NIV)The answer seems to be that the Spirit can be jealous, indeed.
Thanks for reading.
