'Mercy' in the Bible

At that time we took all his towns, and gave them over to complete destruction, together with men, women, and children; we had no mercy on any:

Because the Lord your God is a God of mercy, he will not take away his help from you or let destruction overtake you, or be false to the agreement which he made by an oath with your fathers.

And I will have mercy through a thousand generations on those who have love for me and keep my laws.

And when the Lord has given them up into your hands and you have overcome them, give them up to complete destruction: make no agreement with them, and have no mercy on them:

Be certain, then, that the Lord your God is God; whose faith and mercy are unchanging, who keeps his word through a thousand generations to those who have love for him and keep his laws;

Rewarding his haters to their face with destruction; he will have no mercy on his hater, but will give him open punishment.

And it will be, that if you give attention to these decisions and keep and do them, then the Lord will keep his agreement with you and his mercy, as he said in his oath to your fathers.

Judging uprightly in the cause of the widow and of the child who has no father, and giving food and clothing in his mercy to the man from a strange country.

Do not be guided by him or give attention to him; have no pity on him or mercy, and give him no cover;

Keep not a thing of what is cursed for yourselves: so the Lord may be turned away from the heat of his wrath, and have mercy on you, and give you increase as he said in his oath to your fathers:

And when the Lord your God has given it into your hands, let every male in it be put to death without mercy.

Have mercy, O Lord, on your people Israel whom you have made free, and take away from your people the crime of a death without cause. Then they will no longer be responsible for the man's death.

A hard-faced nation, who will have no respect for the old or mercy for the young:

The Lord will have no mercy on him, but the wrath of the Lord will be burning against that man, and all the curses recorded in this book will be waiting for him, and the Lord will take away his name completely from the earth.
