1 Now Tobit his father counted every day: and when the days of the journey were expired, and they came not, 2 Then Tobit said, Are they detained? or is Gabael dead, and there is no man to give him the money? 3 Therefore he was very sorry. 4 Then his wife said unto him, My son is dead, seeing he stayeth long; and she began to wail him, and said, 5 Now I care for nothing, my son, since I have let thee go, the light of mine eyes. 6 To whom Tobit said, Hold thy peace, take no care, for he is safe. 7 But she said, Hold thy peace, and deceive me not; my son is dead. And she went out every day into the way which they went, and did eat no meat on the daytime, and ceased not whole nights to bewail her son Tobias, until the fourteen days of the wedding were expired, which Raguel had sworn that he should spend there. Then Tobias said to Raguel, Let me go, for my father and my mother look no more to see me. 8 But his father in law said unto him, Tarry with me, and I will send to thy father, and they shall declare unto him how things go with thee. 9 But Tobias said, No; but let me go to my father. 10 Then Raguel arose, and gave him Sara his wife, and half his goods, servants, and cattle, and money: 11 And he blessed them, and sent them away, saying, The God of heaven give you a prosperous journey, my children. 12 And he said to his daughter, Honour thy father and thy mother in law, which are now thy parents, that I may hear good report of thee. And he kissed her. Edna also said to Tobias, The Lord of heaven restore thee, my dear brother, and grant that I may see thy children of my daughter Sara before I die, that I may rejoice before the Lord: behold, I commit my daughter unto thee of special trust; where are do not entreat her evil.
[AD 735] Bede on Tobit 10:1-13
"Alas, alas, my son, why did we send you to travel, the light of our eyes, the staff of our old age, etc." And Tobias, consoling her, responds: "Be quiet and do not be disturbed, our son is safe, etc.," suits those same ones who now believe among the Jews; who still console themselves and their own with this, that truly a time will come when the Lord will return to them, and then all Israel will be saved; knowing that the Lord, who promised this, is faithful. For as we taught above, the same Tobias, by his blindness, signifies the unbelievers, and by his faith, the believers, according to the customary manner of the Scriptures.
Raguel asks Tobias to stay with him for a longer time, but he is not heard, with Tobias saying: "I know that my father and my mother are now counting the days, and their spirit is tormented within them." And when the fullness of the Gentiles has come in, no one will be able to prevent God from granting salvation to Israel and removing the blindness that has happened in part. For divine mercy remembers that there is great sadness and continuous sorrow of heart for those who believe from among the Jews because of the blindness of the unbelievers, who are their relatives according to the flesh, who are Israelites.
Therefore, Raguel sent Tobias back to his parents, giving him Sarah with much substance. In the end, the teachers of the Church send Christ back, with the Church itself full of the riches of virtues, to enlighten with faith and enrich with the substance of good works the Jewish people, from whom He took His flesh.
