I find it funny how we in our minds try to wrangle over where things are in scripture and where exactly was that written.
Here is the Holy Spirit who inspired the writer of Hebrews to say that "It was testified or was said somewhere...."...Do we think the Holy Spirit forgot where the verse was as He was inspiring the writer of the book of Hebrews to write truth?
Hebrews 2:6 (NASB)
[SUP]6 [/SUP] But one has testified somewhere, saying, "WHAT IS MAN, THAT YOU REMEMBER HIM? OR THE SON OF MAN, THAT YOU ARE CONCERNED ABOUT HIM?
Hebrews 4:4 (NASB)
[SUP]4 [/SUP] For He has said somewhere concerning the seventh day: "AND GOD RESTED ON THE SEVENTH DAY FROM ALL HIS WORKS";
KJV calls it "a certain place"....but the Greek word means "somewhere"..
4084. πού pou adv
Somewhere, about, approximately.
