59 And these were they which went up from Tel-melah, Tel-harsa, Cherub, Addan, and Immer: but they could not shew their father's house, and their seed, whether they were of Israel:
And those who came up from Thelmela, etc. In this place, even according to the letter, the grace of God, by which also in the Old Testament the Gentiles were received into salvation, is shown. While a catalogue of those who clearly belonged to the people of God has been listed, some of those whose origins whether from Israel or from proselytes were unknown, are also included, and their number is mentioned among the children of Israel. Even though due to the long separation of their fathers from the temple or the people of God, they couldn't specify how they belonged to them; nevertheless, since they had ascended from captivity when general permission was granted, and hastened with those who unquestionably descended from the seed of Israel to build the temple of God, they were accepted by them as companions. For they were glad to have them as brothers and acquaintances due to the common love of faith and religion, although because of the uncertainty of their carnal origins it seemed they recognized them less. Moreover, in the spiritual sense, among penitents who, liberated from the captivity of vices, ascend to build the house of the Lord either in themselves or in others, there are often some bound by graver sins who appear so estranged from all acts of piety and chastity that none of the goodness and religion they had received from holy teachers seems to remain in them. About these, what else can be said than that they cannot indicate whether they were born from Israel, that is, from the holy Church by believing; for evidently, by sinning, they have become as though they had never belonged to the holy seed; however, through repentance, they sometimes correct themselves and turn to a better life, so that their number is rightfully inscribed among the true Israelites, in whom there is no deceit, in heaven (John 1).
