Genesis 26:12-14

Then Isaac planted [seed] in that land [as a farmer] and reaped in the same year a hundred times [as much as he had planted], and the LORD blessed and favored him. And the man [Isaac] became great and gained more and more until he became very wealthy and extremely distinguished; he owned flocks and herds and a great household [with a number of servants], and the Philistines envied him.
