And there went forth a wind from the LORD, and brought quails from the sea, and let them fall by the camp, as it were a day's journey on this side, and as it were a day's journey on the other side, round about the camp, and as it were two cubits high upon the face of the earth.

Wesley's Notes

11:31 A wind from the Lord - An extraordinary and miraculous wind both for its vehemency and for its effects. Quails - God gave them quails once before, Exo 16:13, but neither in the same quantity, nor with the same design and effect as now. From the sea - Principally from the Red - sea, and both sides of it where, by the reports of ancient Heathen writers, they were then in great numbers, and, no doubt, were wonderfully increased by God's special providence for this very occasion. Two cubits high - Not as if the quails did cover all the ground two cubits high for a day's journey on each side of the camp, for then there had been no place left where they could spread them all abroad round about the camp; but the meaning is, that the quails came and fell down round about the camp for a whole day's journey on each side of it, and that in all that space they lay here and there in great heaps, which were often two cubits high.

King James Translators' Notes

as it were a day's...: Heb. as it were the way of a day

Scofield Reference Notes

[2] two cubits high upon the face of all the earth

The correct rendering is, "about two cubits above the face of the earth," that is, within reach of the people that they might slay them for food. The statement is not that the quails were piled up from the face of the earth two cubits deep. The level of their flight was two cubits above the earth.

Jamieson-Fausset-Brown Bible Commentary

31-35. There went forth a wind from the Lord, and brought quails from the sea, &c.-These migratory birds (see on [76]Ex 16:13) were on their journey from Egypt, when "the wind from the Lord," an east wind (Ps 78:26) forcing them to change their course, wafted them over the Red Sea to the camp of Israel.

let them fall a day's journey-If the journey of an individual is meant, this space might be thirty miles; if the inspired historian referred to the whole host, ten miles would be as far as they could march in one day in the sandy desert under a vertical sun. Assuming it to be twenty miles this immense cloud of quails (Ps 78:27) covered a space of forty miles in diameter. Others reduce it to sixteen. But it is doubtful whether the measurement be from the center or the extremities of the camp. It is evident, however, that the language describes the countless number of these quails.

as it were two cubits high-Some have supposed that they fell on the ground above each other to that height-a supposition which would leave a vast quantity useless as food to the Israelites, who were forbidden to eat any animal that died of itself or from which the blood was not poured out. Others think that, being exhausted with a long flight, they could not fly more than three feet above the earth, and so were easily felled or caught. A more recent explanation applies the phrase, "two cubits high," not to the accumulation of the mass, but to the size of the individual birds. Flocks of large red-legged cranes, three feet high, measuring seven feet from tip to tip, have been frequently seen on the western shores of the Gulf of Akaba, or eastern arm of the Red Sea [Stanley; Shubert].

Matthew Henry's Concise Commentary

11:31-35 God performed his promise to the people, in giving them flesh. How much more diligent men are in collecting the meat that perishes, than in labouring for meat which endures to everlasting life! We are quick-sighted in the affairs of time; but stupidity blinds us as to the concerns of eternity. To pursue worldly advantages, we need no arguments; but when we are to secure the true riches, then we are all forgetfulness. Those who are under the power of a carnal mind, will have their lusts fulfilled, though it be to the certain damage and ruin of their precious souls. They paid dearly for their feasts. God often grants the desires of sinners in wrath, while he denies the desires of his own people in love. What we unduly desire, if we obtain it, we have reason to fear, will be some way or other a grief and cross to us. And what multitudes there are in all places, who shorten their lives by excess of one kind or other! Let us seek for those pleasures which satisfy, but never surfeit; and which will endure for evermore.
