'Show Mercy' in the Bible

and Jehovah your God shall deliver them before you, you shall crush them, completely destroy them. You shall make no covenant with them nor show mercy to them.

And he said, O Jehovah, the God of Israel, there is no God like You in Heaven or in earth. You keep Your covenant and show mercy to Your servants who walk before You with all their hearts.

They lay hold on a bow and spear; they are cruel and will not show mercy. Their voice shall roar like the sea, and they shall ride on horses arrayed like a man for the battle against you, O daughter of Babylon.

For God has shut up all in unbelief, so that He might show mercy to all.
