'Hard' in the Bible

And he shall offer of the sacrifice of the peace offering an offering made by fire unto the LORD; the fat thereof, and the whole rump, it shall he take off hard by the backbone; and the fat that covereth the inwards, and all the fat that is upon the inwards,

Do not make attempts to get equal with one who has done you wrong, or keep hard feelings against the children of your people, but have love for your neighbour as for yourself: I am the Lord.

And if a man from another country is living in your land with you, do not make life hard for him;

Do not be a hard master to him, but have the fear of God before you.

And they will be your children's heritage after you, to keep as their property; they will be your servants for ever; but you may not be hard masters to your countrymen, the children of Israel.
