'Dig' in the Bible

Lay not up for yourselves treasures upon the earth, where moth and rust spoils, and where thieves dig through and steal;

but lay up for yourselves treasures in heaven, where neither moth nor rust spoils, and where thieves do not dig through nor steal;

he is like to a man building a house, who did dig, and deepen, and laid a foundation upon the rock, and a flood having come, the stream broke forth on that house, and was not able to shake it, for it had been founded upon the rock.

And he answering said unto him, Lord, let it alone this year also, till I shall dig about it, and dung it:

Then the steward said within himself, What shall I do? for my lord taketh away from me the stewardship: I cannot dig; to beg I am ashamed.
