What does Genesis 28:4 mean?
Before Jacob heads to Mesopotamia to find a wife, also fleeing the wrath of Esau (Genesis 27:41), Isaac confers on him the covenant promises of God to Abraham. The previous verse included the blessing of many offspring. Now Isaac describes Jacob as possessing the "blessing of Abraham" for his offspring to possess the promised land of Canaan. It's possible that Isaac didn't offer this as part of his initial blessing—intended for Esau—because he knew Esau's temperament and intermarriage made him ineligible for such a promise (Genesis 25:29–34; 26:34–35).God will be faithful to keep His promises to Abraham through Isaac and now through Jacob and his children. Jacob will leave Isaac's household with both Isaac's blessing for wealth and political power and the covenant blessing of God with Abraham for multitudes of offspring and possession of the land.
