Matthew Poole and continuators on Jeremiah 41:5

5 That there came certain from Shechem, from Shilo, and from Samaria , even fourscore men, having their beards shaven, and their clothes rent, and having cut themselves , with offerings and incense in their hands to bring them to the house of the LORD .

Samaria was the name both of a City and a Province, Shechem was a City within that Province, within the limits of the Tribe of Ephraim, Ios. 20.7. These places were now inhabited by a mixt people, partly Jews, partly such as the King of Assyria had upon his Conquest of the Ten Tribes brought to inhabit there; from thence came 80 men,

who possibly had not heard of the Temple being burnt, at least when they came out, or if they had heard of it yet thought, hearing some Iews were left, that they might have erected some Altar for Sacrifices, or it may be they brought no beasts.

For the Text speaks onely of incense and offerings, they came with all indications of mourning used in those Countries, shaven beards, clothes rent, and having cut themselves in a barbarous fashion used by the heathens, and forbidden the Jews, but yet practised by many of them.
