What did Samson carry away from Gaza to a hilltop near Hebron?

Answer: The doors of the city gate

At midnight he pulled up the doors of Gaza's gate with both gateposts and the bar, and carried them on his shoulders.

“When the Gazites heard that Samson was there, they surrounded that place and lay in wait for him all night at the city gate. They were quiet throughout the night, saying, “Let us wait until dawn; then we will kill him.””— Judges 16:2 (BSB)
