Adam Clarke on Judges 16:1

Then went Samson to Gaza, and saw there a harlot - The Chaldee, as in the former case, renders the clause thus: Samson saw there a woman, an inn-keeper. Perhaps the word זונה zonah is to be taken here in its double sense; one who keeps a house for the entertainment of travelers, and who also prostitutes her person. Gaza was situated near the Mediterranean Sea, and was one of the most southern cities of Palestine. It has been supposed by some to have derived its name from the treasures deposited there by Cambyses, king of the Persians; because they say Gaza, in Persian, signifies treasure; so Pomponius Mela and others. But it is more likely to be a Hebrew word, and that this city derived its name, עזה azzah, from עזז azaz, to be strong, it being a strong or well fortified place. The Hebrew ע ain in this word is, by the Septuagint, the Arabic, and the Vulgate, rendered G; hence instead of azzah, with a strong guttural breathing, we have Gaza, a name by which this town could not be recognized by an ancient Hebrew.
