Halakhah sur Ézéchiel 36:20

It is from the roots of the commandment that God chose Israel to be a holy nation and wanted to give them merit. And therefore He guided them and commanded them about the ways of grace and compassion and warned them to crown themselves with every beautiful and precious trait to find grace in the eyes of all who see them, [such] that they will say, "These are the people of the Lord" (Ezekiel 36:20). And it is so much the way of pleasantnesses and beauty to show kindness and to grant good to one who leaves his people and all the family of the house of his father and mother and comes to take shelter under the wings of a different nation in his love for it, and in his choosing of truth and his hatred for falsehood. And in our meriting these good traits, the goodness of God will rest upon us and cling to us, and nothing will prevent us from it; as the good will extend to the good ones and the opposite to the bad ones.
