'Merciful' in the Bible

His servants said to him, “Behold now, we have heard that the kings of the house of Israel are merciful kings, please let us put sackcloth on our loins and ropes on our heads, and go out to the king of Israel; perhaps he will save your life.”

But You, O Lord, are a God merciful and gracious,Slow to anger and abundant in lovingkindness and truth.

The Lord is gracious and merciful;Slow to anger and great in lovingkindness.

The merciful man does himself good,But the cruel man does himself harm.
