Albert Barnes Commentary Judges 18:2

"And the children of Dan sent of their family five men from their whole number, men of valor, from Zorah, and from Eshtaol, to spy out the land, and to search it; and they said unto them, Go, search the land. And they came to the hill-country of Ephraim, unto the house of Micah, and lodged there." — Judges 18:2 (ASV)

This identity of locality with the scene of Samson’s birth and death indicates that both narratives are drawn from the same source, probably the annals of the tribe of Dan.
