2 Chronicles 31:16 Meaning and Commentary

2 Chronicles 31:16

Beside their genealogy of males, from three years old and
upwards
Their office was not only to give to the priests, but to those of their males in their genealogy, who were three years old and upwards; for under that age, according to Kimchi, they were not fit to come into the temple; nor have they knowledge to keep what is put into their hands; nor fit to handle offerings, lest they should defile them; but at that age they might be taught how to hold them, and be used to it; but as for females, he says, they were not admitted at any age:

even unto everyone that entereth into the house of the Lord;
of the said age, and in the genealogy and register of the priests:

his daily portion for their service in their charges, according to
their courses;
food for every day, in consideration of their service in their several wards, according to their courses in turn.

2 Chronicles 31:16 In-Context

14 Kore son of Imnah the Levite was in charge of the special gifts the people wanted to give to God. He was responsible for giving out the contributions made to the Lord and the holy gifts. Kore was the guard at the East Gate.

15 Eden, Miniamin, Jeshua, Shemaiah, Amariah, and Shecaniah helped Kore in the towns where the priests lived. They gave from what was collected to the other groups of priests, both young and old.

16 From what was collected, these men also gave to the males three years old and older who had their names in the Levite family histories. They were to enter the Temple of the Lord for their daily service, each group having its own responsibilities.

17 The priests were given their part of the collection, by families, as listed in the family histories. The Levites twenty years old and older were given their part of the collection, based on their responsibilities and their groups.

18 The Levites' babies, wives, sons, and daughters also got part of the collection. This was done for all the Levites who were listed in the family histories, because they always kept themselves ready to serve the Lord.
