'Uncircumcised' in the Bible

Then his father and his mother said to him, “Is there no woman among the daughters of your relatives, or among all our people, that you go to take a wife from the uncircumcised Philistines?” But Samson said to his father, “Get her for me, for she looks good to me.”

Then he became very thirsty, and he called to the Lord and said, “You have given this great deliverance by the hand of Your servant, and now shall I die of thirst and fall into the hands of the uncircumcised?”
