Is it not strange, that only 600 men went up armed on this occasion, when we know that the tribe of Dan when they first entered Canaan, were more than 64 thousand? Had sin and a departure from the Lord thinned their numbers? A solemn question!
Judges 18:7-11
7 Then the five men departed, and came to Laish,a and saw the people that were therein, how they dwelt careless, after the manner of the Zidonians, quiet and secure; and there was no magistrate in the land, that might put them to shame in any thing; and they were far from the Zidonians, and had no business with any man.
8 And they came unto their brethren to Zorah and Eshtaol: and their brethren said unto them, What say ye?
9 And they said, Arise, that we may go up against them: for we have seen the land, and, behold, it is very good: and are ye still? be not slothful to go, and to enter to possess the land.
10 When ye go, ye shall come unto a people secure, and to a large land: for God hath given it into your hands; a place where there is no want of any thing that is in the earth.
11 And there went from thence of the family of the Danites, out of Zorah and out of Eshtaol, six hundred men appointedb with weapons of war.
