Genesis 26:14
For he had possession of flocks, and possession of herds, and great store of servants: and the Philistines envied him. For he had possession of flocks, and possession of herds, and great store of servants: and the Philistines envied him.
Famine had carried Isaac into the land of the Philistines, and the verse describes his condition in that Philistine country as one abundantly blessed by God there. It belongs to the account of God's providential dealings with Abraham's family, the chosen line through which the Seed would come. It accompanies God's renewing to Isaac the promise of the land and its inheritance, continuing the covenant made with Abraham, and its prosperity accompanies that renewed promise.
The blessing that came upon Isaac reflected Abraham's obedience to God's commands, which included the law of love and care for his children. That obedience teaches that parents should command their children to follow the godly way of life they themselves have practiced. Isaac's greatness in that place came from the Lord's blessing, giving him agricultural prosperity and household wealth with abundant possession of flocks and herds and great store of servants, so that he had become very great.
That abundance of flocks, herds, and servants stirred the envy of the Philistines against him and brought differences with them. The chapter presents God's providential care in working for Isaac when he does not contend for his rights but commits his cause to God, yielding even more than justice requires, with blessing from God in consequence. His visible success gave his neighbors reason to inquire about the principles behind it, including his reliance on God and his faithful practice of worship and stewardship.
