Deep calls to deep

Posted by Mathew K J on May 04, 2007

I've been digging around trying to fully grasp the meaning (or the common English understanding) of a phrase found in Psalm 42:7. The phrase reads as follows:
"Deep calls to deep" (New International Version) "Deep calleth unto deep" (King James Version) "Deep calls unto deep" (New King James Version)

Would help to know. Thanks in advance - Mathew K J (Bangalore, India)
