“Our water we drank for money; our wood comes at a price” (Lamentations 5:4).
“Our water we drank for money.” One time, the tormentors entered and took their bread, their wine, their oil, and their water. They then sold it to them. They said: ‘Woe to us that this verse has been realized in our regard: “Our water we drank for money; our wood comes at a price.”’
