'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}.

The weak you [have] not strengthened, and the sick you [have] not healed, and {with respect to} the hurt you have not bound [them up], and you [have] not brought back the scattered, and you [have] not sought the lost, but [rather] you ruled over them with force and with ruthlessness.
