'Diggeth' in the Bible

and Isaac turneth back, and diggeth the wells of water which they digged in the days of Abraham his father, which the Philistines do stop after the death of Abraham, and he calleth to them names according to the names which his father called them.

And he removeth from thence, and diggeth another well, and they have not striven for it, and he calleth its name Enlargements, and saith, 'For -- now hath Jehovah given enlargement to us, and we have been fruitful in the land.'
