The lot is cast into the lap; but the whole disposing thereof is of the LORD. The lot is cast into the lap - On the lot, see the note on Numbers 26:55. How far it may be proper now to put difficult matters to the lot, after earnest prayer and supplication, I cannot say. Formerly, it was both lawful and efficient; for after it was solemnly cast, the decision was taken as coming immediately from the Lord. It is still practiced, and its use is allowed even by writers on civil law. But those who need most to have recourse to the lot are those who have not piety to pray nor faith to trust to God for a positive decision. The lot should never be resorted to in indifferent matters; they should be those of the greatest importance, in which it appears impossible for human prudence or foresight to determine. In such cases the lot is an appeal to God, and he disposes of it according to his goodness, mercy, and truth. The result, therefore, cannot be fortuitous.
