'Shown Mercy' in the Bible

The Lord has devoured; he has not shown mercy to all the dwellings of Jacob; he has broken down in his wrath the fortifications of the daughter of Judah; he has leveled to the ground, he has dishonored the kingdom and its commanders.

Yahweh has done what he has planned; he has fulfilled his promise that he ordained from the days of old; he has demolished and not shown mercy; he has made an enemy rejoice over you, he has exalted the {might} of your foes.

They lie in [the] soil of [the] streets, young and old; my young women and young men, they have fallen by the sword; you have slain on the day of {your anger}, you have slaughtered and not shown mercy.

You have covered [yourself] {in anger} and pursued us, you have slain and not shown mercy.
