Wisdom 12:19

19 But by such works hast thou taught thy people that the just man should be merciful, and hast made thy children to be of a good hope that thou givest repentance for sins.

Wisdom 12:19 In-Context

17 For when men will not believe that thou art of a full power, thou shewest thy strength, and among them that know it thou makest their boldness manifest.
18 But thou, mastering thy power, judgest with equity, and orderest us with great favour: for thou mayest use power when thou wilt.
19 But by such works hast thou taught thy people that the just man should be merciful, and hast made thy children to be of a good hope that thou givest repentance for sins.
20 For if thou didst punish the enemies of thy children, and the condemned to death, with such deliberation, giving them time and place, whereby they might be delivered from their malice:
21 With how great circumspection didst thou judge thine own sons, unto whose fathers thou hast sworn, and made covenants of good promises?
