Genesis 26:1, 12

Now there was a famine in the land [of Canaan], besides the previous famine that had occurred in the days of Abraham. So Isaac went to Gerar, to Abimelech king of the Philistines.

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.
