2 Chronicles 31:16

16 They were appointed to distribute them to males who were at least three years old. The way they were enrolled in the genealogical records did not matter. The six men who served under Kore were to distribute the offerings to everyone who went to the LORD's temple to perform the daily service that each division was responsible for.

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 the gatekeeper at East Gate and had to take care of the freewill offerings made to God. His responsibility was to distribute the offerings made to the LORD and the holy gifts dedicated to God.

15 Eden, Miniamin, Jeshua, Shemaiah, Amariah, and Shecaniah served under him in the cities belonging to the priests. They were to distribute the offerings faithfully to all their relatives, young and old, by their divisions.

16 They were appointed to distribute them to males who were at least three years old. The way they were enrolled in the genealogical records did not matter. The six men who served under Kore were to distribute the offerings to everyone who went to the LORD's temple to perform the daily service that each division was responsible for.

17 They were to distribute offerings to the priests who were enrolled by families and to the Levites who were at least 20 years old. Distribution was based on the way they served in their divisions.

18 The priests and Levites were enrolled with their wives, sons, daughters, and other people who depended on them--the whole community. The priests and Levites had to be faithful in keeping themselves holy for the holy work.
