6 Then the woman came and told her husband, saying, A man of God came unto me, and his countenance was like the countenance of an angel of God, very terrible: but I asked him not whence he was, neither told he me his name:
[AD 397] Ambrose of Milan on Judges 13:2-7
After the spirit of the Hebrews had been so subdued by the pressure of a long subjection that no one dared with a manly spirit to rouse them to liberty, Samson, fore-ordained by the Divine oracle, was raised up to them. A great man he was, not one of the multitude, but first among the few, and beyond controversy far excelling all in bodily strength. And he is to be regarded by us with great admiration from the beginning, not because in his early abstinence from vice he gave signal proofs of temperance and sobriety, nor on account of his long preserving as a Nazarite his locks unshorn, but because from his very youth, which in others is an age of softness, he achieved illustrious deeds of virtue, perfect beyond the measure of human nature. By these he gained credence to the Divine prophecy, that it was not for nothing that such grace had gone before upon him, that an Angel came down by whom his birth beyond their hopes was announced to his parents, to be the leader and protector of his countrymen, now for a length of years harassed by the tyranny of the Philistines.

His father was of the tribe of Dan, a man fearing God, born of no mean rank, and eminent above others, his mother was barren of body, but in virtues of the mind not unfruitful; seeing that in the sanctuary of her soul she was counted worthy to receive the visit of an Angel, obeyed his command and fulfilled his prophecy. Not enduring however to know the secrets even of God apart from her husband she mentioned to him that she had seen a man of God, of beautiful form, bringing her the Divine promise of future offspring, and that she, confiding in this promise, was led to share with her husband her faith in the heavenly promises.

[AD 735] Bede on Judges 13:2-7
Thus Jacob, the patriarch Joseph, Samson, [who was] the bravest of the chieftains, and Samuel, [who was] the most distinguished of the prophets, [all] had as their progenitors [mothers who were] for a long time barren in body but always fruitful in virtues. In this way their dignity would be known from the miraculous nativity of those who were born, and it might be proven that they would be famous in their lives, since at the very outset of their lives they transcended the norms of the human condition.
