Grandchildren are the crown of the aged, and the glory of children is their fathers.
Proverbs 17:6 ESV

A God-fearing father teaches his children to be the same, and they teach their children. God-fearing grandchildren are like a victory laurel wreath to a man, confirming in the eyes of all others that he has done well. In turn, the inheritance of righteousness that he has passed on to his children will bring them honor in the eyes of both God and man.
