פּירוש אויף בראשית 26:26

וַאֲבִימֶ֕לֶךְ הָלַ֥ךְ אֵלָ֖יו מִגְּרָ֑ר וַאֲחֻזַּת֙ מֵֽרֵעֵ֔הוּ וּפִיכֹ֖ל שַׂר־צְבָאֽוֹ׃

און אבֿימֶלֶך איז געגאַנגען צו אים פֿון גרָר, מיט אַחוזַת זײַן גוטן פֿרײַנט, און פּיכול דעם האַר פֿון זײַן חיל.

Rashi

ואחזת מרעהו —as the Targum renders it: וסיעת מרחמוחי which means a company formed from his friends, the מ meaning from סיעת ממאוהביו. There are some who explain that in מרעהו the מ is part of the noun מרע — just like (Judges 14:11) “Thirty companions (מרעים)” in the narrative of Samson — in order that the word ואחזת should be taken to be the construct state to מרעהו (the company of his friends). But it would not be a polite thing to speak thus of a king — the company of his friends — for if this were the meaning it would imply that he (Abimelech) took with him the whole company of his friends and that he had no more than one group of friends. For this reason it should be interpreted in the first way (that אחזת is not construct). And you need not be surprised at the ת of אחזת although the word is not in the construct state, for we have similar cases in Scripture: (Psalms 60:13) “help (עזרת) against the adversary”, and (Isaiah 51:21) “Drunken, (שכרת) but not with wine”.

Rashbam

מרעהו ואחזת, with an entourage of his friends, as per Onkelos. The expression מרעהו occurs in this sense in Judges 15,6. The prefix מ in the word מרעהו is similar to the same prefix in the מריע ותוקע (Rosh Hashanah 33) [an unusual shift from the simple active mode kal, to the causative mode hiphil for basically the same activity, namely blowing the shofar. Ed.] as well as the מ in Jeremiah 21,4 אנכי מסב את כלי המלחמה, “The author quotes several more examples, as for instance, Proverbs 12,26 יתר מרעהו צדיק, ודרך רשעים תתעם, “the righteous enjoys advantages over his fellow man; the way of the wicked leads him astray.” [If I understand correctly, the letter מ is used transitively, although in this instance in the construction of a noun. Avimelech’s entourage רעהו was meant to give moral support to Avimelech in this ordinarily humiliating undertaking for him. Rash’bam goes as far as understanding the word ויתורו in Numbers 13,2 not as commonly understood as a verbal form of תור, “to tour, to traverse,” but as related to the word יתר from יתרון quoted in his citation from Proverbs 12,26. As to the fact that, if so, he word in Numbers should have been ויתירו instead of ויתורו, he quotes the interchangeable usage or ישוב and ישיב as well as יקום and יקים as examples where the hiphil is also used with the letter ו instead of the letter י for the middle root letter, עיו הפועל. Ed.]

Radak

ואבימלך...ואחוזת מרעהו, Avimelech had a powerful minister whose name was Achuzat (Bereshit Rabbah 64,9) The Massoretes claim that the word is not the name of a human being. Accordingly, the word מרעהו would have to be understood as similar to Kings I 4,5 רעה המלך, “a companion of the king, a close friend.” The leading minister, comparable to a prime minister in a constitutional monarchy, always had the title רע המלך, “the King’s closest associate.” The letter מ in the word מרעהו belongs to the groups of letters known as אותיות א-מ-ת-י-ן which often are used as additional letters. For instance, we find this extraneous letter מ in connection with רע also in Judges 14,20 ותהי אשת שמשון למרעהו אשר רעה לו, “Shimshon’s wife then married one of those who had been his wedding companion.” Onkelos translates the words אחוזת מרעהו as “a group of his supporters.” Accordingly, the verse means that Avimelech took with him a number of his close advisers, friends. According to Onkelos the meaning of the letter מ in the word מרעהו is a mem hashimush, a formative letter varying pronoun endings, etc., so that the word רעהו would be the same as רעיו, His companions, and the unusual plural ending, the same as in Nachum 2,4 מגן גבוריהו, “his warriors’ shields.” The word גבוריהו is an alternate for גבוריו.

Rashi

אחזת signifies a collection and band, and a band is so called because the people who constitute it are held נאחזין together.
