דברים כה ,ב: וְהָיָה אִם -ב ִן הַּכ וֹת הָרָ שׁ ָע And it will be if he is a son of (deserving) flogging
Baal HaTurim comments on why is the word "bin" vowelized with a "chirik" rather than with a "segol." This teaches us that we must use "binoh" wisdom when administering flogging. Firstly, even if a person transgressed a prohibition, there are six types of sins that do not carry the flogging penalty. Secondly, even if the sinner is to be flogged, it must be done with great calculation. We do not automatically give him the full 39 floggings. He might be too weak to receive them all. Also, when the court administers less then 39, they must be in multiples of three.
According to Onkelos, the word בִן of our verse is a form of the word בֶן, which usually means “son of”, but also can mean “student of”. The form of the word בֶן appears more than 1500 times in Tanach. However the form of the word בִן appears only 33 times (28 times it is used in reference to Yehoshua).
Baal HaTurim cites another example אגור בִן יקח, which is a name used by King Shlomo in reference to himself (Mishlei 30,1). Baal HaTurim suggests that the word בִן is connected to בינה (understanding), as is Yehoshua, a person of understanding.
