Divrey Hayamim Alef 23:24

24 These were the Bnei Levi after the bais avoteihem; even the rashei avot, as they were counted by number of shmot by their head count, that did the work for the avodas Beis Hashem, from the age of twenty shanah and upward.

Divrey Hayamim Alef 23:24 Meaning and Commentary

1 Chronicles 23:24

These were the sons of Levi, after the house of their fathers,
&c.] According to the three classes of them, as descending from the three sons of Levi:

[even] the chief of the fathers;
or heads of families:

as they were counted by number of names by their polls;
or according to their heads, one by one:

that did the work for the service of the house of the Lord;
the particulars of which are in ( 1 Chronicles 23:28-31 )

from the age of twenty years, and upwards;
they were first numbered thirty and upwards, ( 1 Chronicles 23:3 ) , but David before his death ordered they should be numbered from twenty and upwards, ( 1 Chronicles 23:27 ) , because the Israelites being increased, there would be more work for the priests in the temple, which would require the assistance of more Levites. The reasons follow.

Divrey Hayamim Alef 23:24 In-Context

22 And Eleazar died, and had no banim, only banot, and their brethren the Bnei Kish took them as wives.

23 The Bnei Mushi; Machli, and Eder, and Yeremot, three.

24 These were the Bnei Levi after the bais avoteihem; even the rashei avot, as they were counted by number of shmot by their head count, that did the work for the avodas Beis Hashem, from the age of twenty shanah and upward.

25 For Dovid said, Hashem Elohei Yisroel hath given rest unto His people, that they may dwell in Yerushalayim ad l’olam;

26 And also unto the Levi’im; they shall no more carry the Mishkan, nor any kelim (vessels) of it for the avodah thereof.
