ציטירנדיקער פּירוש אויף במדבר 32:2

The heads of the tribes: According to my opinion that this section is after the war with Midian, it is for this reason that [the section about that war] is after it; just as "And Miriam and Aaron spoke about Moses (Numbers 12:1) is after "and they were in Chatserot" (Numbers 11:35) [even though it happened earlier], as I explained.1 And Scripture states that the Children of Gad came to Moses and Elazar and the princes of the congregation and they spoke their words. And afterwards, it is written (Numbers 32:28), "Then Moses gave instructions concerning them to Elazar the priest, Joshua son of Nun, and the family heads of the Israelite tribes" - which are the princes of the congregation [just] mentioned. And since Moses said to the Children of Gad and the Children of Reuben (Numbers 32:24), "you shall do what comes out of your mouth"; it is therefore written (Numbers 30:2), "And Moses spoke to the heads of the tribes," and then (verse 3), "he shall do like everything that comes out of his mouth."

לפני משה [THEY STOOD] BEFORE MOSES, and afterwards לפני אלעזר, BEFORE ELEAZAR?! But is it possible if Moses did not know what reply to give them that Eleazar should know it? Rather, invert the words of the text and so expound it (before Eleazar and before Moses). This is the view of R. Josiah; but Abba Chanan said in the name of R. Eleazar that this inversion is unnecessary: they were sitting in the House of Study and they (the daughters of Zelophehad) stood before all of those who were present (Sifrei Bamidbar 133:3; Bava Batra 119b and Rashi on Numbers 9:6).

ותאמר לאה בגד, “Leah said: ‘good fortune has come.’” Some commentators, in zeroing in on the name גד, point out that members of the tribe of Gad were the first ones to receive their ancestral portion of land in the land of Israel, as documented in Numbers 32,2 “the members of the tribes of Gad and Reuven came, etc.” Other commentators hold that that the word בגד means that Leah said: “now I know that my husband has betrayed me, seeing that he has taken my maid servant as a competing wife.” When Avraham took Hagar he had not had any children by Sarah. When Rachel gave her maid servant to Yaakov, she too had not born any children for him. But I have born my husband four children, so there was no reason for him to take her as a wife. If, nonetheless I have started being capable of having children again this must be my reward for allowing him to take my maid servant. When she bore another son she called him אשר to reinforce this feeling of joyous gratitude to G’d Who had blessed her with 6 sons.
