The Fox is saying - Perek Shira - Chapter 5

Shu'al omer. Hoy boneh veito belo tzedek va'aliyotav belo mishpat bere'ehu ya'avod chinnam ufo'alo lo yitten lo

The Fox is saying: “Woe to him that builds his house without justice, and his chambers without lawfulness; that uses his friend’s service without wages, and does not give him for his hire.”
