'Oppressing' in the Bible

As a result, whenever the LORD raised up leaders for them, the LORD remained present with their leader, delivering Israel from the control of their enemies during the lifetime of that leader. The LORD was moved with compassion by their groaning that had been caused by those who were oppressing and persecuting them.

So the five men left and went to Laish, and observed the people who were living there carefree, as Sidonians tend to do, in peace and quiet. There was no ruler in the land oppressing them for any reason. They were living far away from the Sidonians, and had no dealings with anyone.
