'Five' in the Bible
These nations included the five lords of the Philistines, all of the Canaanites, the Sidonians, and the Hivites who lived in Mount Baal-hermon as far as Lebo-hamath.
So the tribe of Dan sent from their families five valiant men of their number from Zorah and Eshtaol to scout the land and search through it. Following their orders, which were "Go and scout the land," they came to the mountainous region of Ephraim, arrived at Micah's home, and stayed there.
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.
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."
the five men who had gone to scout out the land arrived, entered Micah's home and confiscated the carved image, the ephod, the household idols, and the cast image. Meanwhile, the priest stood outside by the entrance to the gate with the 600 men armed with military weapons.
