Judges 14:5 (KJV)

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.

But his father and his mother knew not that it was of the Lord, that he sought an occasion against the Philistines: for at that time the Philistines had dominion over Israel.

Then went Samson down, and his father and his mother, to Timnath, and came to the vineyards of Timnath: and, behold, a young lion roared against him.

And the Spirit of the Lord came mightily upon him, and he rent him as he would have rent a kid, and he had nothing in his hand: but he told not his father or his mother what he had done.

And he went down, and talked with the woman; and she pleased Samson well.
