The start of the verse suggests the encampment was at Kiriath-jearim itself. But then the end of the verse notes that Mahaneh-dan (Camp of Dan
) was actually west of Kiriath-jearim.
This location, though sharing the same name, was different from where Samson started out in Judges 13:25.
12 and went up and encamped at Kiriath-jearim in Judah. On this account that place is called Mahaneh-dan to this day; behold, it is west of Kiriath-jearim.
