'Ruthlessness' in the Bible

You shall not rule over him with ruthlessness, but you shall revere your God.

And you may pass them on as an inheritance to your sons after you to take possession of as property {for all time}--you may let them work. But [as for] your countrymen, the {Israelites}, you shall not rule with ruthlessness over {one another}.

He shall be with him {as a yearly hired worker}; he shall not rule over him with ruthlessness {in your sight}.

You haven't strengthened the weak, treated the sick, set broken bones, regathered the scattered, or looked for the lost. Instead, you've dominated them with brutal force and ruthlessness.
