On the Duties of the Clergy — Historical footnotes

76. A man’s disposition ought to be undefiled and sound, so that he may utter words without dissimulation and possess his vessel in sanctification; that he may not delude his brother with false words nor promise aught dishonourable. If he has made such a promise it is far better for him not to fulfil it, rather than to fulfil what is shameful.

78. Never shall I be led to believe that the leader Jephtha made his vow otherwise than without thought, when he promised to offer to God whatever should meet him at the threshold of his house on his return. For he repented of his vow, as afterwards his daughter came to meet him. He rent his clothes and said: “Alas, my daughter, thou hast entangled me, thou art become a source of trouble unto me.” And though with pious fear and reverence he took upon himself the bitter fulfilment of his cruel task, yet he ordered and left to be observed an annual period of grief and mourning for future times. It was a hard vow, but far more bitter was its fulfilment, whilst he who carried it out had the greatest cause to mourn. Thus it became a rule and a law in Israel from year to year, as it says: “that the daughters of Israel went to lament the daughter of Jephtha the Gileadite four days in a year.” I cannot blame the man for holding it necessary to fulfil his vow, but yet it was a wretched necessity which could only be solved by the death of his child.

80. That example of Jephtha’s daughter is far more glorious and ancient than that of the two Pythagoreans, which is accounted so notable among the philosophers. One of these, when condemned to death by the tyrant Dionysius, and when the day of his death was fixed, asked for leave to be granted him to go home, so as to provide for his family. But for fear that he might break his faith and not return, he offered a surety for his own death, on condition that if he himself were absent on the appointed day, his surety would be ready to die in his stead. The other did not refuse the conditions of suretyship which were proposed and awaited the day of death with a calm mind. So the one did not withdraw himself and the other returned on the day appointed. This all seemed so wonderful that the tyrant sought their friendship whose destruction he had been anxious for.
