Leviticus 25:43

Verse Leviticus 25:43. Thou shalt not rule over him with rigour] What is rigorous service? "Service which is not determined, and service whereof there is no need." This is the definition given by the Jews; but much more is implied in this command than is expressed here. Labour beyond the person's strength, or labour too long continued, or in unhealthy or uncomfortable places and circumstances, or without sufficient food, c., is labour exacted with rigour, and consequently inhuman and this law is made, not for the Mosaic dispensation and the Jewish people, but for every dispensation and for every people under heaven.
