'Mercy' in the Bible

Therefore let us [with privilege] approach the throne of grace [that is, the throne of God’s gracious favor] with confidence and without fear, so that we may receive mercy [for our failures] and find [His amazing] grace to help in time of need [an appropriate blessing, coming just at the right moment].

Anyone who has ignored and set aside the Law of Moses is put to death without mercy on the testimony of two or three witnesses.

and to Jesus, the Mediator of a new covenant [uniting God and man], and to the sprinkled blood, which speaks [of mercy], a better and nobler and more gracious message than the blood of Abel [which cried out for vengeance].
