Genesis 26:16

Go—for thou art much, &c.— In consequence of the envy arising from Isaac's prosperity, Abimelech desired him to leave his country. That this envy was joined with fear, is evident as well from the expression, for thou art much mightier than we, as from Genesis 26:28. See Exodus 1:9. We are to remember, that princes and princedoms in those days were but petty and inconsiderable: and if Abraham so many years before could arm three hundred and eighteen of his own domestics, ch. Genesis 14:14. we may well believe that Isaac's family was much more extensive.
