Egli andava di anno in anno facendo il giro di Bet-El, di Ghilgal e di Mizpa, e giudicava Israele in tutti questi luoghi.
Metzudat David
The Lord shall judge the ends of the earth: Meaning to say, You O Lord, please let my son judge the ends of the land, to be a judge in Israel and to go around in the places of their cities, to judge them. And this was likewise fulfilled, as it is written (I Samuel 7:16), "And he went, etc. and made the rounds, etc. and judged Israel."
Rashbam
והמם מהומה גדולה, the construction of והמם, i.e. the vowel pattern of two successive letters מ and the two vowels kametz in succession is clearly parallel to וסבב בית אל in Samuel I 7,16 with the two letters ב, or as in Lamentations 5,18 שמם from שממה. The meaning of the phrase is that G’d made these people hear such powerful and earsplitting noise during the battle that this contributed greatly to their destruction. If we were to assume that the second letter מ is a pronoun ending meaning אותם, “them,” the vowel pattern should have been vehamaman. Seeing that the root of the word is המה as in יהמה לבי (Jeremiah 48,36) “my heart moans, etc.”, the Torah wrote vehamam, i.e. “He made them moan.” We find a line with similar meaning in Isaiah 48,5 עצבי עשם, “my carved images were the cause of this,” the word עשם being derived from the root עשה, or Genesis 29,10 כאשר ראה יעקב something which is referred to later in Genesis 32,3 as כאשר ראם, “when he saw them.” The root המה determines the construction here.
If you were to say that the final letter ם was a sign of the pronoun “them,” as in the examples from Isaiah and Lamentations we have quoted, this is impossible, as the expression המיון, which implies something that is part of the human body, as in Isaiah 16,11 and Jeremiah 48,36, or in Psalms 46,4 יהמו יחמרו מימיו, “its waters rage and foam;” i.e. this is self-generated, not the result of action by outsiders. If the word were in the transitive mode, hiphil, the vowel pattern would have had to be vehimah, just as in the root כלה, for instance, the vowel pattern if it appeared in the transitive mode, hiphil, the vowel pattern would have to be kilah. Or it would have to be כלם, kilam as the case would be if the final letter ם were used as the pronoun ending for “them,” as in Lamentations 2,22 or 4,11. When used transitively, the root שנה meaning changing, exchanging, such as clothes, would be שנא, shina, in the plain past tense, as in Kings II 25,29, or וישניה, vayehshaneha, in the past tense introduced by the letter ו changing a future mode to a past mode, as in Esther 2,9.

Rashi
והמתי I WILL CONFOUND — This is equivalent to וְהָמַמְתִּי (i. e. the root is המם). Its rendering in the Targum is ואשנש “and I will confound”. Similar is every verb the root of which has its last letter doubled (verbs ע"ע): when it is changed (conjugated) to express the idea of “I have done something” (i. e. the first person singular perfect of the Kal; the same really applies to some inflected forms of other conjugations also) there are occasions when one omits the doubled letter (it is actually the first of the two similar letters) and dageshes the remaining letter of these two and vowels it with מלאפום (our חולם). Examples are: וְהַמֹּתִי which is of the same derivation as, (Isaiah 28:28) “and the wheel of his cart makes a confused noise (המם)”; (Ecclesiastes 2:20) וְסַבֹּתִי, “and I turned about” which is of the same derivation as, (I Samuel 7:16) “and he went round (וסבב) to Bethel”; (Psalms 116:6) דַלֹּתִי “I was low”, of the same derivation as, (Isaiah 19:6) “The waters shall become low (דללו) and dried up”; (Isaiah 49:16) “I have graven thee (חַקֹּתִיךְ) upon the palms of my hand”, of the same derivation as, (Judges 5:15) “things engraved (חקקי) in the heart”; (I Samuel 12:3) את מי רַצֹּתִי “whom have I crushed”, of the same derivation as, (Job 20:19) “because he hath crushed (רצץ) and hath forsaken the poor”. He, however, who translates it in the Targum by וְאֶקְטַל , is in error. For if it were derived from the root denoting death (מות), the ה in it would not be vowelled with Patach and its מ would not be dageshed nor vowelled with חולם, but it would read וְהַמַתִּי, as, (Numbers 14:15) “Now if Thou shalt kill (וְהַמַתָּ) this people”, the ת being dageshed because it would come in place of two ת’s, one being a root-letter — for no form of מות can be written without at least one ת (that in the root) — and the other being a servile letter (part of the suffix), just as תִּי in אמר-תי and חמא-תי and עשי-תי. Similarly with נתתי: the second ת is dageshed because it comes in the place of two ת’s — since it (the word) really requires three ת’s, two for the root, as in, (Joshua 10:12) “the day when the Lord giveth (תת)”, and in, (Ecclesiastes 3:13) “it is the gift (מתת) of God”, — and the third as a servile letter.
