'Be Merciful' in the Bible

Be merciful LORD unto thy people Israel which thou hast delivered and put not innocent blood unto thy people Israel: and the blood shall be forgiven them.'

"And so the LORD will not be merciful unto him, but then the wrath of the LORD and his jealousy, smoke against that man, and all the curses that are written in this book light upon him, and the LORD do out his name from under heaven,

"Rejoice, heathen with his people, for he will avenge the blood of his servants, and will avenge him of his adversaries, and will be merciful unto the land of his people."
