The division and arrangement begins very properly in the house of Aaron; for Aaron himself was called of God. Hebrews 5:4. And it was worthy observation that the appointment of this man's family to the offices assigned them, was done by lot. The apostles of Jesus did the same in filling up the vacancy of the traitor Judas. This was done by lot, accompanied with earnest prayer that the Lord's choice, and not man's, might be known and attended to. If this were made the plan now, instead of human caprice, fancy, interest, and humour, would it not be more scriptural, and more likely to produce blessings? Acts 1:24.
1 Chronicles 24:1-18
1 Now these are the divisions of the sons of Aaron. The sons of Aaron; Nadab, and Abihu, Eleazar, and Ithamar.
2 But Nadab and Abihu died before their father, and had no children: therefore Eleazar and Ithamar executed the priest's office.
3 And David distributed them, both Zadok of the sons of Eleazar, and Ahimelech of the sons of Ithamar, according to their offices in their service.
4 And there were more chief men found of the sons of Eleazar than of the sons of Ithamar; and thus were they divided. Among the sons of Eleazar there were sixteen chief men of the house of their fathers, and eight among the sons of Ithamar according to the house of their fathers.
5 Thus were they divided by lot, one sort with another; for the governors of the sanctuary, and governors of the house of God, were of the sons of Eleazar, and of the sons of Ithamar.
6 And Shemaiah the son of Nethaneel the scribe, one of the Levites, wrote them before the king, and the princes, and Zadok the priest, and Ahimelech the son of Abiathar, and before the chief of the fathers of the priests and Levites: one principala household being taken for Eleazar, and one taken for Ithamar.
7 Now the first lot came forth to Jehoiarib, the second to Jedaiah,
8 The third to Harim, the fourth to Seorim,
9 The fifth to Malchijah, the sixth to Mijamin,
10 The seventh to Hakkoz, the eighth to Abijah,
11 The ninth to Jeshua, the tenth to Shecaniah,
12 The eleventh to Eliashib, the twelfth to Jakim,
13 The thirteenth to Huppah, the fourteenth to Jeshebeab,
14 The fifteenth to Bilgah, the sixteenth to Immer,
15 The seventeenth to Hezir, the eighteenth to Aphses,
16 The nineteenth to Pethahiah, the twentieth to Jehezekel,
17 The one and twentieth to Jachin, the two and twentieth to Gamul,
18 The three and twentieth to Delaiah, the four and twentieth to Maaziah.
