'Merciful' in the Bible

and forgive Your people who have sinned against You and all the transgressions which they have committed against You, and make them objects of compassion before their captors, that they will be merciful to them

And his servants said unto him, Behold now, we have heard that the kings of the house of Israel are merciful kings: let us, I pray thee, put sackcloth on our loins, and ropes upon our heads, and go out to the king of Israel: peradventure he will save thy life.
