Maybe 90-something? Joshua ran out to wallyworld for a machine to move that "great stone," but the passage doesn't say

anything about wagons or winches.  Perhaps, that detail is given elsewhere - but, for some reason, i think Joshua 24:29 gives the full account.   A "great stone."  Uhm, sounds heavier than 250 pounds.  How did the old man, "stricken in years," (Joshua 13:1) lift big rocks and battle - not just 2-legged desert-rats, but - full blown anakims?  Btw, concerning the stone, neither does the passage mention Joshua pointing to the stone, and telling four or five young warriors to "set it up there."
