Indeed.. these concepts were foreign to ALL other languages and cultures.. for they came from and were inspired by God(the real one).. since the Jews (when/after they became Jews).. were dealt with the real God.. Certain Hebrew words were unique to what God was doing with the hebrews.. like Messiah.. Holy.. Shekinah.. Angel.. in the unique hebrew sense..
Joseph Campbell (the study of myth) missed this unique event.. God(the real one) choosing(even constructing) a certain group of people.. on this planet for a particular TASK..
I strongly agree with you that God chose Israel - and the Hebrew language - for a reason. Moreover, I assert that we can benefit from understanding ancient Hebrew word concepts - especially as those word concepts are translated into Greek word concepts.
