4 But not this, but many other grounds for confidence ought we to have. For God has already given us not a few pledges for favourable hopes. And first of all, those who carried the evil tidings departing hence with the speed of wings, supposing they should long ere this have reached the camp, are yet delayed in the midst of their journey. So many hindrances and impediments have arisen; and they have left their horses, and are now proceeding in vehicles; whence their arrival must of necessity be retarded.
For since God here stirred up our priest, and common father, and persuaded him to go forth, and undertake this embassy, he detained the messengers for a while, when they were but half way on their road, lest arriving before him they might kindle the fire, and make our teacher's efforts to mend matters useless, when the royal ears had become inflamed. For that this hindrance on the road, was not without God's interposition is evident from this. Men who had been familiar with such journeys all their lives, and whose constant business it was to ride on horseback, now broke down through the fatigue of this very riding; so that what has now happened is the reverse of what took place in the case of Jonah.
For God hastened him when unwilling, to go on his mission. But these, who were desirous to go, He hindered. O strange and wonderful event! He wished not to preach of an overthrow; and God forced him to go against his will. These men with much haste set forward to be the bearers of a message of overthrow, and against their will again He has hindered them! For what reason think you? Why, because in this case the haste was an injury; but in the other case, haste brought gain. On this account, He hastened him forward by means of the whale; and detained these by means of their horses.
Do you see the wisdom of God? Through the very means by which each party hoped to accomplish their object, through these each received an hindrance. Jonah expected to escape by the ship, and the ship became his chain. These couriers, by means of their horses, expected the more quickly to see the Emperor; and the horses became the obstacles; or rather, neither the horses in one case, nor the ship in the other, but the Providence of God everywhere directing all things according to its own wisdom!
