Judges 16:3

And Samson lay till midnight, and arose at midnight, and took the doors of the gate of the city, and the two posts, and went away with them, bar and all, and put them upon his shoulders, and carried them up to the top of an hill that is before Hebron.

Cross-reference

In Judges 16:20, Samson later loses his strength and is captured—contrasting sharply with his triumph here.

Psalm 107:16 describes God shattering bronze doors and iron bars—the very feat Samson accomplishes by removing Gaza's gates.

Micah 2:13 speaks of a 'breaker' who goes up and breaks through the gate—Samson is that breaker here, leading himself out.

1 Samuel 23:7 has Saul thinking gates and bars trap David—but Samson here removes them to escape, reversing the expectation.
