'Cast' in the Bible

O you foolish and thoughtless and superficial Galatians, who has bewitched you [that you would act like this], to whom—right before your very eyes—Jesus Christ was publicly portrayed as crucified [in the gospel message]?

But what does the Scripture say?“Cast out the bondwoman [Hagar] and her son [Ishmael],For never shall the son of the bondwoman be heir and share the inheritance with the son of the free woman.”
