Ambrose of Milan, on Judg 14:1

Now Samson, approved by such signal tokens from above, turned his thoughts as soon as he grew up, to marriage; whether this was that he abhorred those vague and licentious desires in which young men are wont to indulge, or that he was seeking an occasion of releasing the necks of his countrymen from the power of the hard yoke of the Philistines. Wherefore going down to Timnath, (this is the name of a city situated in those parts where the Philistines then dwelt,) he beheld a maiden of a pleasing form and beautiful countenance, and he besought his parents, by whoso company he was supported in his journey, to ask her for him in marriage. But they, not knowing that his intention, either, if the Philistine refused her to him, to be more fierce against them, or, if they assented, to remove their disposition to injure their subjects; and since from such a connexion a certain equality and kindliness of intercourse would naturally grow, or, on the other hand, if any offence were given, this desire of revenge would be more vehement, deemed that this maiden ought to be avoided as a foreigner. But after they had vainly attempted to change the purpose of their son by urging upon him these lawful objections, they of their own accord acquiesced in his desire.
