'Need' in the Bible

Then the five men who had gone to scout out the territory of Laish told their relatives, "Are you aware that in these houses there's an ephod, some household idols, a carved image, and a cast image? You know what you need to do."

Meanwhile, we also have straw and fodder for our donkeys, and bread and wine for me, for this young woman servant, and for the young man who is with your servants. We don't need anything else."
