'Uncircumcised' in the Bible

But his father and mother said to him, "Is there not a wife among the daughters of your relatives, or among all our people, that you must take a wife from [the] uncircumcised Philistines?" But Samson said to his father, "Take her for me because {she pleases me}."

And he was very thirsty, and he called to Yahweh and said, "You gave this great victory into the hand of your servant, but now I must die of thirst and fall into the hand of the uncircumcised?"
