John Wesley on 2 Chronicles 35:5

Stand - Or, minister, (as that word is frequently used) in the court of the priests. According - According to the several families both of the people, whom he calls their brethren, lest they should despise them, or grudge to serve them, and of the Levites. For the passover was to be eaten by the several families according to their numbers, and therefore he commands these persons, that when the paschal lambs were brought to them to be killed, they might so order the matter, that they might be distributed to the several families whether of the Levitical or other tribes.
