'Split open' in the Bible

When he had finished speaking all these words, the ground that was under them split open,

So God split open the basin at Lehi and water flowed out from it. When he took a drink, his strength was restored and he revived. For this reason he named the spring En Hakkore. It remains in Lehi to this very day.

That day he also announced a sign, "This is the sign the Lord has predetermined: The altar will be split open and the ashes on it will fall to the ground."

The altar split open and the ashes fell from the altar to the ground, in fulfillment of the sign the prophet had announced with the Lord's authority.
