1 Then Tobias called Raphael, and said unto him, 2 Brother Azarias, take with thee a servant, and two camels, and go to Rages of Media to Gabael, and bring me the money, and bring him to the wedding. 3 For Raguel hath sworn that I shall not depart. 4 But my father counteth the days; and if I tarry long, he will be very sorry. 5 So Raphael went out, and lodged with Gabael, and gave him the handwriting: who brought forth bags which were sealed up, and gave them to him. 6 And early in the morning they went forth both together, and came to the wedding: and Tobias blessed his wife.
[AD 735] Bede on Tobit 9:1-6
Therefore, Raphael, taking four of Raguel’s servants and two camels, went to Rages of the Medes; and, informing him about everything concerning Tobias, received the money and brought him with him to the wedding. Raguel’s servants and camels are preachers chosen from among the Gentiles, through whom the Lord also gathers others. Servants, because they serve the necessity of those to whom they preach the gospel. Camels, because they bear the burdens of their weaknesses with fraternal submission of charity. Why there are four servants and two camels was shown above, where two cows and four rams are killed. Such, with the help of Raphael, bring Gabael to Tobias's wedding when holy preachers, with divine assistance, gather new peoples into the unity of the Church of Christ.
