Psalms 44:10

10.Thou hast made us to turn back from the enemy. Here the people of God still further complain, that he had made them to flee before their enemies, and had given them up as a prey to be devoured by them. As the saints firmly believe that men are strong and valiant only in so far as God upholds them by his secret power, they also conclude, that when men flee, and are seized with trembling, it is God who strikes them with terror, so that the poor wretched creatures are deprived of reason, and both their skill and courage fail them. The expression here used is taken from the Law, Deuteronomy 32:30, where Moses says,

“How should one chase a thousand, and two put ten thousand to flight, except their Rock had sold them, and the Lord had shut them up?”

The faithful, fully persuaded of this truth, do not ascribe to fortune the change which had passed over them, that those who were wont vigorously and fearlessly to assail their enemies, were now terrified by their very appearance; but they feel assured that it was by the appointment of heaven that they were thus discomfited, and made to flee before their enemies. And as they formerly confessed that the strength which they had hitherto possessed was the gift of God, so, on the other hand, they also acknowledge that the fear by which they are now actuated was inflicted upon them as a punishment by God. And when God thus deprived them of courage, they say that they are exposed to the will of their enemies; for in this sense I interpret the word למו, lamo, which I have rendered, for themselves, namely, that their enemies destroyed them at their pleasure and without any resistance, as their prey.
