'Be Merciful' in the Bible

Hearken therefore unto the prayers of thy servant and of thy people Israel, which they pray in this place. But hear thou out of thy dwelling place heaven: and when thou hearest it, be merciful.

Then hear thou from heaven and be merciful unto the sin of thy people Israel, and bring them again unto the land which thou gavest to them and to their fathers.

Then hear thou from heaven and be merciful unto the sin of thy servants and of thy people Israel, that thou show them a good way to walk in, and send rain upon thy land which thou hast given unto thy people, for an inheritance.

thou shalt hear from heaven thy dwelling place, and shalt be merciful, and give every man according unto all his way, even as thou shalt know every man's heart: for thou only knowest the hearts of the children of Adam:

Then hear from heaven, thy dwelling place, their supplication and prayers and judge their cause, and be merciful unto thy people, though they have sinned against thee.

Yet if my people that are named after my name, shall humble themselves and pray and seek my presence, and turn from their wicked ways, then will I hear from heaven and be merciful to their sins, and will heal their land.

"The good LORD be merciful to all that set their hearts to seek the God that is the LORD God of their fathers, though they do it not according to the cleanness of the holy place."
