'Uncircumcised' in the Bible

Then his father and his mother said unto him, Is there never a woman among the daughters of thy brethren, or among all my people, that thou goest to take a wife of the uncircumcised Philistines? And Samson said unto his father, Get her for me; for she pleaseth me well.

And he was sore athirst, and called on Jehovah, and said, Thou hast given this great deliverance by the hand of thy servant; and now shall I die for thirst, and fall into the hand of the uncircumcised.
