'Split open' in the Bible

All the people followed him, playing flutes and rejoicing with such a great joy that the earth split open from the sound.

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.
