ציטירנדיקער פּירוש אויף משלי 14:21

Rabbi Yehoshua ben Chananya--happy is the one who gave birth to him!: The undifferentiated expression, 'happy' is a category that includes all of the virtues through which a person is happy. And when it mentions the trait [with it], it is [referring only to] a particular [trait]. And we have found it stated about fear as in "Happy is the man who fears the Lord" (Psalms 112:1). And also about the designation of a fixed place for Torah [study], as it is written (Proverbs 8:34), "Happy is the man who listens to me, coming early to my gates each day, waiting outside my doors," and it states (Psalms 84:5), "Happy are those who dwell in Your house; they will still forever praise You." And about devotion, as it is stated (Psalms 65:5), "Happy is the man You choose and bring near to dwell in Your courts." And about faith (Psalms 84:6), "Happy is the man who has refuge in You." It is also stated about one who prevents himself from [involvement with] evildoers (Psalms 1:1), "Happy is the man who has not followed the counsel of the evildoers, or taken the path of sinners, or joined the company of the scorners." It is also stated about those that keep the Shabbat (Isaiah 56:2), "Happy is the man who does this." It is also stated about those that walk in the Torah of the Lord (Psalms 119:1), "Happy are those whose way is blameless, who follow the Torah of the Lord." It is also stated about those that keep the commandments (Psalms 119:2), "Happy are those who observe His decrees, who turn to Him wholeheartedly." It is also stated about one who benefits from his toil (Psalms 128:2), "You shall enjoy the fruit of your labors; you shall be happy and it shall be good for you." It is also stated about those that keep the law and do justice (Psalms 106:3), "Happy are those who act lawfully, who do justice at all times." It is also stated about trust [in God] (Proverbs 16:20), "he who trusts in the Lord is happy." It is also stated about wisdom (Proverbs 3:13), "Happy is the man who finds wisdom," and it is also written (Proverbs 14:21), "he who shows pity for the lowly is happy." And about this is it said, "happy is the one who gave birth to him" undifferentiated; meaning to say he is happy with all of the happy traits - great in his wisdom and refined by his traits and in all of his affairs.

what is a straight path that a person should cling to: From all of the good and straight paths that a person should cling to. He means to say to cling to one trait, to be complete with it. As it is better for a person to grab one trait in full - that it become easy for him to reach all of the important traits via it - than his being someone with [attempted mastery of] many traits and he is not complete in any one of them. And this is that which Rabbi Eliezer said, A good eye: He means to say the trait of generosity, which is a fine and praiseworthy trait. And once he is at the peak of generosity, he will certainly reach the other virtues - as this trait [comes] to him because of a broad heart and a good eye. And a person like this is fit for every good trait, and this is what is written (Proverbs 14:21)," he who shows pity (mechonen) for the lowly is happy." This means to say that the humble are the ones that find favor in his eyes and [so] he gives to them with a good eye. [This is like] the usage (Psalms 102:15), "and they will cherish (mechonen) its dust" - that the dust of the Land of Israel will find favor in their eyes.
