In Judges 1:16 (NASB)
Now the descendants of the Kenite, Moses’ father-in-law, went up from the city of palms with the sons of Judah, to the wilderness of Judah which is in the south of Arad; and they went and lived with the people.
Yet, the same verse in Good News Translation
The descendants of Moses' father-in-law, the Kenite, went on with the people of Judah from Jericho, the city of palm trees, into the barren country south of Arad in Judah. There they settled among the Amalekites.
What's the reason for this difference?
