하닷이 죽고 마스레가의 삼라가 그를 대신하여 왕이 되고
Sforno
ומלכים מחלציך יצאו. This blessing means that the Jewish people would always possess persons who are fit to occupy the throne, as opposed to the Edomites who, as we know from 36,36-37, had to rely repeatedly on outsiders to become their kings.
Radak
אלוף אהליבמה. This Oholivamah was a male. This is so in spite of the fact that his name ends with the letter ה suggesting that the person mentioned was a female. The same name occurs elsewhere for females in this very chapter (verse 5). Other males whose names conclude with the letter ה are שמלה, מסרקה in verse 36. Timna was a concubine of Eliphaz, although the name of one of the Alufim of Esau was also Timna. (verse 40)
