Judges 14:2-6

So he came back and told his father and mother, “I saw a woman in Timnah, one of the daughters of the Philistines; so now, get her for me as a wife.”

But 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?” Yet Samson said to his father, “Get her for me, because she is right for me.”

However, his father and mother did not know that this was of the Lord, for He was seeking an occasion against the Philistines. And at that time the Philistines were ruling over Israel.

Then Samson went down to Timnah with his father and mother, and came as far as the vineyards of Timnah; and behold, a young lion came roaring toward him.

And the Spirit of the Lord rushed upon him, so that he tore it apart as one tears apart a young goat, though he had nothing in his hand; but he did not tell his father or mother what he had done.
