Thomas Aquinas, on Ps 49:10

“For all the beasts of the woods are mine: the cattle on the hills, and the oxen.”

“"For all the beasts of the forests are mine." He proves what he said, namely that he approves neither calves nor goats, and that if he were in need, he would not accept them from their house. No one asks for something that is in his own power; but all things that they offered were in the power of God. Three things were offered in the Old Covenant: four-footed animals, birds, and fruits, namely first-fruits and bread. With respect to the first he says, "All the beasts of the forests are mine." Four-footed animals are divided into two kinds: some are wild and some domestic. And although wild animals were not offered, yet he enumerates them to make it more apparent that even the domestic ones are his. Mystically, moreover, various kinds of persons can be designated by these animals. Hence he says, "wild beasts," that is, unbelievers; "beasts of burden," that is, the faithful; "oxen on the mountains," that is, the apostles -- all are mine.”
