The Torah, summarizing the construction of the Mishkan, mentions: בְצַלְאֵל בֶּן אוּרִי בֶן חוּר לְמַטֵּה יְהוּדָה, “Bezalel, son of Uri son of Hur, of the tribe of Judah did everything that Hashem commanded Moshe.” (Ex. 38,22) Why was it necessary for the Torah to go back in history and mention Bezalel’s grandfather and his tribe? Usually, in Jewish practice, when identifying a person, only his name and the name of his father are given.
Chazal tell us that when people are active in community work they should do so for the sake of heaven, because then זכות אבותם מסייעתן, “the merit of their fathers will aid them”.
Community workers may have the feeling that they can do as they please and that they are not accountable to anyone. By mentioning Bezalel’s ancestry the Torah is telling us that one should always keep in mind his background, his parents and their parents. By remembering them, their memory will aid them in doing their work honestly and faithfully for the cause.
The saying is, “power corrupts”. This may be true, but recalling whence we stem from may help overcome the trend.
