Prov. 12:10, “A [consistently] righteous man regards the life of his beast, but the tender mercies of the wicked are cruel.”  Deut. 25:4, “You shall not muzzle the ox when he treads out the grain.” See also 1 Cor. 9:9-10; 1 Tim. 5:17-18.  Exo. 23:4-5 stands for the proposition that God expects man to care for his animals. It requires man to bring back a lost animal even to his enemy and requires that a man help his enemy to release his animal from too heavy a burden. Exo. 23:12 reveals the Sabbath—a day of rest—was made so that the ox and donkey—the beast of burdens could rest.

Deut. 22:6-7 stands for the principle of protecting wild life.  It says that the eggs or young can be taken from a nest, but not the mother bird.  The Bible promises that if the wildlife conservation is practiced—it will bring long life to the people who practice it. Also see Lev. 25:7 where every seven years a field must rest from being tilled and the crops that grow on the land that year may not be harvested, but they are to furnish food for the poor, the aliens, and for not only domestic beasts but wild animals shall be fed by those crops.
