Genesis 26:16

And Abimelech said unto Isaac, Go from us; for thou art much mightier than we.

Cross-reference

In Genesis 26:27, Isaac asks why they've come after 'ye hate me, and have sent me away' — directly recalling this expulsion.

Exodus 1:9 Allusion

In Exodus 1:9, Pharaoh alarms his people saying Israel has grown 'more and mightier' — the same fear of a growing people that drives Abimelech here.
