'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

But his servants said to him, “We have heard that the kings of the house (royal line) of Israel are merciful kings. Please let us put sackcloth around our loins and ropes on our necks [as symbols of submission], and go out to the king of Israel; perhaps he will spare your life.”
