Charles H. Spurgeon on Psalms 78:26

He caused an east wind to blow in the heaven: and by his power he brought in the south wind. Here, on examining the geographical position of the Israelites, we see exactly how the south east wind would bring the quails. The Israelites had just passed by the Red Sea, and had began to experience a foretaste of the privations which they were to expect in the desert, through which they had to pass. Passing northwards in their usual migrations, the birds would come to the coast of the Red Sea, and there would wait until a favourable wind enabled them to cross the water. The south east wind afforded them just the very assistance which they needed, and they would naturally take advantage of it. J. G. Wood, in "Bible Animals." 1869.
