And if he have betrothed her unto his son, he shall deal with her after the manner of daughters.
God gave Israel laws framed in infinite wisdom and equity, not left to human guessing. These were not arbitrary rules but a Theocracy's constitution, suited to make them happy. The Israelites had suffered under Egyptian cruelty; now that they held power over servants, provision was made to ensure they would not replicate that abuse. Those who have felt the whip themselves have no excuse to wield it.
