Musar do Malachiasza 1:6

'A son will honor his father, and a servant his master.' A son will honor his father, as it is written: 'Honor your father and your mother,' which they explained: 'with food and with drink and the like.' This, during the life of his father. Now lest you say that after his father dies, he is exempt from this, this is not so, for [in this respect, too,] it is written: 'Honor your father.' For if the son walks in crooked paths, he certainly shames his father; he certainly humiliates him. But if that son walks in a just path and corrects his misdeeds, he certainly honors his father. He honors him in this world before people; he honors him in the world to come before the Holy One Blessed be He. The Holy One Blessed be He pities him [the father] and places him in his seat of honor. Happy are the tzaddikim, who merit holy sons, holy offspring, of whom it is written (Isaiah 61:9): 'All who see them will defer to them, for they are seed blessed of the L-rd.'"
