John Wesley on 1 Chronicles 24:5

By lot - That the disposal thereof might be of the Lord, and so all contention be prevented, as no man could be charged with partiality, nor could any say, they had wrong done them. In like manner Matthias was chosen to the apostleship by lot with prayer. And I know not, says Mr. Henry, but it might be still used in faith, in parallel cases, as an instituted ordinance. Of God - Or rather, of the things of God, that is, of all persons ministering in the sanctuary, and of all holy ministrations done in it, and of all other matters of the Lord, as they are called by way of distinction from, the king's matters, 2Chron 19:11.
