וַיֹּ֣אמְר֔וּ יְרֻשַּׁ֥ת פְּלֵיטָ֖ה לְבִנְיָמִ֑ן וְלֹֽא־יִמָּחֶ֥ה שֵׁ֖בֶט מִיִּשְׂרָאֵֽל׃
他們說：«便雅憫劫後倖存的人必須保住產業，免得以色列中有一個支派被除滅。»
Rashi
The survivors must inherit the ancestral property The tribe's ancestral property remains unclaimed; let us devise a plan whereby they may father children, so that the property will fall into the possession of the remaining survivors, and a tribe will not be obliterated from Yisroel.
