사사기 11:7의 Halakhah

And, according to this, if one wanted to leave his business partner, thinking that others would join in partnership with him, and in the end, this did not materialize (as also a groom from his shidduch [match]), it is forbidden to reveal this [intention] to his first partner, even though the matter had been heard before three or more, as we have written in section 3. For certainly he [the first partner] will hold it against his partner for wanting to leave him, as it is written (Judges 11:7): "And why do you come to me [Yiftach] now, when you are in distress?" And this might be cause for the dissolution of their partnership or for the first to distress the second, as the Rambam writes (Hilchoth Deoth 7:5): "And if one tells another things… that lead his friend to be harmed in his body or in his possessions or to be distressed or frightened, this is lashon hara."
