'Hollowed' in the Bible

The princes dug the well;the nobles of the people hollowed it outwith a scepter and with their staffs.They went from the wilderness to Mattanah,

He dug a pit and hollowed it outbut fell into the hole he had made.

Now the pillars, [the] height of one pillar [was] eighteen cubits, and a thread of twelve cubits surrounded it, and its thickness [was] four fingers, hollowed out.
