Mercy; clemency to offenders, and bounty to worthy and to indigent persons; and truth; faithfulness in keeping his word and promises inviolably; preserve the king, because they engage God to guard him, and gain him the reverence and affections of his people, which is a king's greatest safety and happiness. Mercy is again mentioned, to show that although it be an act of grace, and therefore in some sort free, yet princes are obliged to it, both by their duty and by their interest, because it is a singular means of their preservation.
