Albert Barnes Commentary Judges 16:3

"And Samson lay till midnight, and arose at midnight, and laid hold of the doors of the gate of the city, and the two posts, and plucked them up, bar and all, and put them upon his shoulders, and carried them up to the top of the mountain that is before Hebron." — Judges 16:3 (ASV)

Instead of forcing the doors open, he tore the posts up, as it were, by the roots, with the barred doors attached to them. The word rendered “went away with them” means “to pluck up the tent-pins,” and hence, “to remove.” The present town of Gaza (Ghuzzeh) is an open town, without gates or walls, but the sites of the ancient gates still remain visible. One of these, on the southeast, is shown as the gate carried off by Samson.

A partially-isolated hill, about half-an-hour southeast of Gaza, and standing out from the chain that runs up to Hebron, bears the name of “Samson’s Mount.” But it may be doubted whether one of the hills overlooking Hebron is not actually meant.
