What does Judges 16:3 mean?

But Samson stayed in bed only until midnight. Then he got up, grabbed the doors of the city gate along with the two posts, pulled them out, put them on his shoulders, and carried them to the top of the hill facing Hebron. Judges 16:3 - Modern Text Bible

(Instead of being caught, Samson leaves in the middle of the night, ripping out the city gates and carrying them far away—a show of strength and defiance.)
