The returning exiles were offered the “help” of a group of “people of the land” in their God-given and king approved task of rebuilding the temple. They chose to turn that offer down. These were actually adversaries seeking to disrupt the work. This was shown in the review of subsequent history. From that time on, the people of the land (leftovers from syncretistic Samaria) made sure that the rebuilding would not happen. They had been wolves in sheep’s clothing.
LORD, give us discernment, so that we know who our real allies are.
Ezra 4
