Genesis 26:16 YLT

¹⁴  and he hath possession of a flock, and possession of a herd, and an abundant service; and the Philistines envy him,

¹⁵  and all the wells which his father's servants digged in the days of Abraham his father, the Philistines have stopped them, and fill them with dust.

¹⁶  And Abimelech saith unto Isaac, 'Go from us; for thou hast become much mightier than we;'

¹⁷  and Isaac goeth from thence, and encampeth in the valley of Gerar, and dwelleth there;

¹⁸  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.
