and made their lives bitter with difficult labor in brick and mortar and in all kinds of fieldwork. They ruthlessly imposed all this work on them.

They ruthlessly oppressed the Israelites that eighteenth year -- that is, all the Israelites living east of the Jordan in Amorite country in Gilead.

So he attacked them ruthlessly in a massive slaughter, then left to live in the caves of Etam.

Its breaking will be like when potters' vessels are broken, shattered so ruthlessly that among its fragments not even a broken sliver will be found for taking fire from a hearth or scooping water out of a cistern."
