Adam Clarke on Psalms 111:5

He hath given meat - טרף tereph, Prey. This may allude to the quails in the wilderness. The word signifies what is taken in hunting - wild beasts, venison, or fowls of any kind; particularly such as were proper for food. It also signifies spoil taken from enemies. And he may also refer to the wondrous manner in which they were fed and supported during their captivity; and by his support he proved that he was mindful of his covenant. He had promised such blessings; he was faithful to his promises.
