Psalm 50:10 — 11, “for every beast of the forest is Mine the cattle on a thousand hills. I know every bird in the mountains, and the creatures of the field are Mine.” The early twentieth century is when mankind began to confine the animals we raise for food, until then the majority spent much of their time in a more free range situation. The confinement was not for the benefit of the animals, it was for convenience and profitability of man.
