וְרֹאשָׁם֙ לֹ֣א יְגַלֵּ֔חוּ וּפֶ֖רַע לֹ֣א יְשַׁלֵּ֑חוּ כָּס֥וֹם יִכְסְמ֖וּ אֶת־רָאשֵׁיהֶֽם׃
Mereka tidak boleh mencukur gundul kepala mereka, dan tidak boleh membiarkan rambut mereka tumbuh panjang; mereka harus memangkas rambut kepala mereka dengan rapi.
Tze'enah Ure'enah
“They shall not shave their heads” [44:20]. The hair of their head should not grow very long and they should not cut off their hair completely. However, they should cut their hair once a month and the haircut should be handsome. The Talmud says in [tractate Sanhedrin] chapter 10. A king cuts his hair every day, the high priest cuts his hair every Friday, and an ordinary priest cuts his hair once a month.2B. Sanhedrin, 22b; Yalkut Shimoni, Ezekiel, Remez, 383.
Rashi
And [the hair of] their heads they are not to shave to remove all the hair.
Rashi
but also not to let it grow wild They may not let their hair grow very long.
Rashi
they must be careful to trim [Heb. כָּסוּם יִכְסְמוּ, (to cut the hair so that it appears)] like spelt (כֻּסֶמֶת), which is arranged on the ear [with] the end of one beside the root of another. So I heard in the name of Rabbi Menahem of blessed memory. It is possible to explain it as an expression for a measure of a medium thing, neither shearing [all the hair of] the head nor letting the hair grow long, but a medium amount, amo(d)ler in O.F., to cut to medium length.
