Samson spent half the night with the prostitute; then he got up in the middle of the night and left. He grabbed the doors of the city gate, as well as the two posts, and pulled them right off, bar and all. He put them on his shoulders and carried them up to the top of a hill east of Hebron.

Samson took hold of the two middle pillars that supported the temple and he leaned against them, with his right hand on one and his left hand on the other.
