'Opening' in the Bible

And after entering the house, they saw the Child with Mary His mother; and they fell down and worshiped Him. Then, after opening their treasure chests, they presented to Him gifts [fit for a king, gifts] of gold, frankincense, and myrrh.

When they were unable to get to Him because of the crowd, they removed the roof above Jesus; and when they had dug out an opening, they let down the mat on which the paralyzed man was lying.

Does a spring send out from the same opening both fresh and bitter water?
