Heap: When Joshua took the city of Ai
(Joshua 8:1)ff he burned it and "made it
an heap [Heb. tel] for ever"
(Joshua 8:28) The ruins of this city were
for a long time sought for in vain. It has been at length, however,
identified with the mound which simply bears the name of "Tel."
"There are many Tels in modern Palestine, that land of Tels, each Tel
with some other name attached to it to mark the former site. But the
site of Ai has no other name 'unto this day.' It is simply et-Tel,
'the heap' par excellence."
