“And Elisha died, and they buried him... And it came to pass that as they were burying a man, that behold, they saw a band of men [Moabites], and they cast the man into the grave of Elisha: and as soon as he touched the bones of Elisha, he revived and stood up on his feet” (IV Kings 13:20-21).
I think you are referring to 2 Kings 13:20-21.
The miracle of Elisha’s bones:
Elisha asked for a double portion of the power God gave Elijah, who was recorded as peforming seven miracles. The ‘touching the bones’ miracle was Elisha’s 14th.
Those ‘pallbearers’ involved had to abort their burial plans for the dead man when they spied the approach of the band of Moabites. They had no time, ditch the body and run. I’m sure if they’d had the slightest hint that that miracle would happen, the text would have stated that as their plan.
So that passage is the RC/EO basis for digging up corpses?
Well, go ahead, knock yourselves out.
