Genesis 26:12 MSG

[12] Isaac planted crops in that land and took in a huge harvest. God blessed him. The man got richer and richer by the day until he was very wealthy. He accumulated flocks and herds and many, many servants, so much so that the Philistines began to envy him. They got back at him by throwing dirt and debris into all the wells that his father’s servants had dug back in the days of his father Abraham, clogging up all the wells.
