[22] By this means Moses pacified the people, and restrained them from stoning him, and brought them to repent of what they were going to do. And because he thought the necessity they were under made their passion less unjustifiable, he thought he ought to apply himself to God by prayer and supplication; and going up to an eminence, he requested of God for some succor for the people, and some way of deliverance from the want they were in, because in him, and in him alone, was their hope of salvation; and he desired that he would forgive what necessity had forced the people to do, since such was the nature of mankind, hard to please, and very complaining under adversities. Accordingly God promised he would take care of them, and afford them the succor they were desirous of. Now when Moses had heard this from God, he came down to the multitude. But as soon as they saw him joyful at the promises he had received from God, they changed their sad countenances into gladness. So he placed himself in the midst of them, and told them he came to bring them from God a deliverance from their present distresses. Accordingly a little after came a vast number of quails, which is a bird more plentiful in this Arabian Gulf than any where else, flying over the sea, and hovered over them, till wearied with their laborious flight, and, indeed, as usual, flying very near to the earth, they fell down upon the Hebrews, who caught them, and satisfied their hunger with them, and supposed that this was the method whereby God meant to supply them with food. Upon which Moses returned thanks to God for affording them his assistance so suddenly, and sooner than he had promised them.
