וַיִּשְׁלַ֤ח מֹשֶׁה֙ לְרַגֵּ֣ל אֶת־יַעְזֵ֔ר וַֽיִּלְכְּד֖וּ בְּנֹתֶ֑יהָ ויירש [וַיּ֖וֹרֶשׁ] אֶת־הָאֱמֹרִ֥י אֲשֶׁר־שָֽׁם׃
And Moses sent to spy out Jazer, and they took the towns thereof, and drove out the Amorites that were there.
Rashi on Numbers
וישלח משה לרגל את יעזר AND MOSES SENT TO SPY OUT JAAZER — The spies captured it (as the text goes on to state, “and they captured it”). They said: We will not do as the former spies, for we have confidence in the power of Moses’ prayer to be able to fight against it (Midrash Tanchuma, Chukat 24).
Sforno on Numbers
וילכדו בנותיה, the spies whom Moses had sent captured Bnot Yaazer.
Siftei Chakhamim
The spies captured it. Since it is written “they captured its surrounding villages” with וילכדו ["they captured"] in the plural form, rather than וילכד ["he captured"] in the singular form, as it does shortly where it is written ויורש ["and he inherited"] in the singular. Rather [this implies that] the spies captured the surrounding villages.
