'Have Mercy' in the Bible

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

And he said, I will make all the light of my being come before you, and will make clear to you what I am; I will be kind to those to whom I will be kind, and have mercy on those on whom I will have mercy.

and said, "If I have found grace in thy sight O Lord, then let my Lord go with us - for it is a stubborn people. And have mercy upon our wickedness and our sin, and let us be thine inheritance."
