וַיִּבְרַח יִפְתָּח מִפְּנֵי אֶחָיו וַיֵּשֶׁב בְּאֶרֶץ טוֹב וַיִּתְלַקְּטוּ אֶל יִפְתָּח אֲנָשִׁים רֵיקִים וַיֵּצְאוּ עִמּוֹ
Jephthah fled from his brothers and dwelled in the land of Tov. Worthless people gravitated towards Jephthah and they went out with him.
Yiftach (Jephthah) was a great military strategist but he was one of the most flawed of our nation’s Judges. The Talmud (Baba Kama 92b) wishes to illustrate the point that “a tree bearing bad fruit travels among barren trees” (i.e., likeminded people gather together). One of its proofs is this verse, in which “empty” people were attracted to Yiftach.
