The ancients; the princes or rulers, as it is explained in the next clause, who are oft called elders, because such were commonly and fitly chosen out of those who were ripe in years. Eaten up; destroyed instead of preserving and dressing it, as you should have done. The vineyard; the church and commonwealth of Israel, which is oft called God's vineyard, as Psalms 80:8,14,15 Isa 5:1 Jeremiah 2:21, &c., and here the vineyard, by way of eminency; or, the vineyard which was committed to your care to keep. The spoil of the poor; the goods which you have violently taken away from the poor.
