Tekelu has nothing to do with Hebrew “shekel”: it signifies either belonging to a Central Asian Teke tribe ( currently in Turkmenistan/Afghanistan) or just a geographical descent from South Anatolia, Sanjak of Antalya (Teke), vilayet of Konya. 
 
Making historical conclusions from homophonic words is a fallacious occupation. One acquaintance of mine tried to convince me that the capital of Poland, Warszawa, was originally called Beer Sheva and was established by Abraham himself:-) 
 
I can go point by point, but it would be an unending game... 
 
Just as an example: how about Sica and Hebrew Sakin ( just a “ knife”)? 
 
Best wishes.
