'Uncircumcised' in the Bible

Then his father and his mother said to him, "Is there never a woman among the daughters of your brothers, or among all my people, that you go to take a wife of the uncircumcised Philistines?" Samson said to his father, "Get her for me; for she pleases me well."

He was very thirsty, and called on Yahweh, and said, "You have given this great deliverance by the hand of your servant; and now shall I die for thirst, and fall into the hand of the uncircumcised?"
