Judges 2:5

And they called the name of that place Bochim
Which signifies "weepers", from the general lamentation of the people, which before had another name; very probably it was Shiloh itself since all Israel was gathered together, the tabernacle being now at Shiloh, and also because sacrifices were offered up, as follows:

and they sacrificed there unto the Lord;
to atone for the sins they had committed; and if they did this in the faith of the great sacrifice of the Messiah, they did well; however, so far there was an acknowledgment of their, guilt, and a compliance with the appointments of God directed to in such cases.
