'Mercy' in the Bible

"A voice [is] heard on [the] barren heights, the weeping of the pleas for mercy of the children of Israel, because they have perverted their way, they have forgotten Yahweh their God.

[The] bow and [the] short sword they grasp [are] cruel, and they show no mercy. Their sound roars like the sea, and on horses they ride, drawn up like a man for battle against you, O daughter of Zion."

With weeping they will come, and with pleas for mercy I will bring them; I will let them walk by streams of water in a straight path. They will not stumble in it, for I have become to Israel a father, and Ephraim, he [is] my firstborn."

They keep hold of bow and short sword. They [are] cruel and they have no mercy. Their sound [is] like the sea, it roars, and upon horses they ride. Drawn up for battle as a man for the battle, against you, O daughter of Babylon.
