AND HE HAD POSSESSIONS OF FLOCKS, AND POSSESSIONS OF HERDS, AND A GREAT HOUSEHOLD, meaning she-asses and camels, he-asses, and men-servants and handmaids. Now Scripture mentions these but not silver and gold, as it says concerning Abraham,¹⁶⁷Ibid., 13:2. because the wealth which he amassed in the land of the Philistines consisted of flocks and a great household.¹⁶⁸Since these possessions which Isaac accumulated in the land of the Philistines were visible to all, the Philistines became jealous of him. Ramban thus explains the beginning and end of this verse as cause and effect. And the Philistines were jealous of him in this matter. This is the meaning of that which Abimelech says to Isaac, For thou art become much mightier than we.¹⁶⁹Verse 16 here. The king said to him, “I, too, who am the king do not have in my home such flocks and domestics as you, and it is a disgrace to us that your household is greater than that of the king.”

ועבודה רבה, work in the field and vineyards. The expression עבודה, unless defined differently, additionally, always refers to labour in the field.
