'Boulder' in the Bible

The angel, who was God, replied, "Take the meat and the unleavened bread and lay them on this boulder. Then pour out the broth." So he did that.

The angel of the LORD extended the tip of the staff that was in his hand and touched the meat and unleavened bread. Fire broke out from inside the boulder, consuming the meat and unleavened bread. Then the angel of the LORD vanished in front of him.

So Manoah prepared a young goat and a grain offering and offered it on a boulder to the LORD, who kept on performing miracles while Manoah and his wife watched continually.
