(1) rests upon direct commandments in the Law Exodus 20:10; Exodus 23:4-5;
(2) connects itself with the thought that the mercies of God are over all His works, and that man’s mercy, in proportion to its excellence, must be like His Jonah 4:11; and
(3) has perpetuated its influence in the popular morality of the East.
