Doing The Good and The Right

(18) And do right and good in the eyes of the Lord. The contextual meaning of this verse is, keep God's commandments, testimonies, and laws, and prepare them to do what is good and right in God's eyes alone. And for "it may go well with you," (Deuteronomy 6:18b) it is a promise. It says, that by doing what is good in God's eyes it will be good for you, because God brings what is good to those who are good and right in their hearts. And our Rabbis in the beautiful midrash (BK 100a) said: This refers to a compromise, acting beyond the strict demands of the law. And the intention of this is that from the beginning God said to keep God's commandments, testimonies, and laws as God has commanded them. And now, it says: even regarding what God did not command, pay attention to do what is good and right in God's eyes, because God loves goodness and righteousness. And it is important because it is impossible to mention in the Torah (what should be) everyone's conduct; with their neighbors and friends, in any business matter, and regarding ordinances of any town or country, because the Torah already mentions many of these laws, such as: "Do not gossip" (Leviticus 19:16); "You shall not take vengeance or bear a grudge" (Leviticus 19:18); "You shall not stand idly by the blood of your neighbor" (Leviticus 19:16); "You shall not insult the deaf" (Leviticus 19:14); "You shall rise before the aged" (Leviticus 19:32), etc. Once more for emphasis, generally one should do what is good and right regarding everything, including compromise, acting beyond the strict demands of the law. - (Other examples of that can be found in rabbinic literature) like what was mentioned regarding "the law of one whose field borders the field of his neighbor" (BM 108a); and even what they said, (Regarding the depiction of the worthy prayer leader) “and his youth was becoming and he is humble and accepted by the people,” (Taanit 16a); and "he does not speak pleasantly with other people" (Ioma 86a) - until one reads about all matters of honesty and integrity.

The Sages of Neharde’a say: Even if his claim was due to the halakha of one whose field borders the field of his neighbor, we still remove him, as it is stated: “And you shall do that which is right and good in the eyes of the Lord” (Deuteronomy 6:18). One should not perform an action that is not right and good, even if he is legally entitled to do so.
