Genesis 20:10

And Abimelech said unto Abraham ,.... Continuing his discourse with him:

what sawest thou, that thou hast done this thing ? he desires to know what he had observed, either in him or his people, that gave him any reason to conclude that they were a lustful people, and would stick at nothing to gratify their lusts, which put him upon taking such a method to secure his life, lest they should kill him for his wife's sake.
