גָּ֖ד גְּד֣וּד יְגוּדֶ֑נּוּ וְה֖וּא יָגֻ֥ד עָקֵֽב׃ (ס)
Si Gad — mga pangkat ng hukbo ang lalabas mula sa kanya, at siya'y babalik sa sarili niyang mga bakas.
Rashi
גד גדוד יגודנו GAD, AN ASSAILING TROOP SHALL ASSAIL HIM — all the words in this verse which have, the letters גד are connected in meaning with the word גדוד and so also did Menachem ben Seruk classify them. Should you say, however, that גדוד has always two ד’s and these words have only one, the answer is: The word גדוד is a noun and therefore requires two ד’s, for it is the way of a biliteral root to have the second letter doubled when used as a noun; the root proper, however, consists only of two letters. Thus it says, (Proverbs 26:2) כצפור לנוד “the wandering sparrow”, (לנוד a verb, infinitive) of the same derivation as נדודים in (Job 7:4) “I am full of גדודים wanderings” (a noun); (Judges 5:27) ‘‘there he fell down (שדוד) dead”, a noun in meaning, which is of the same derivation as the verb in (Psalms 41:6) “that wasteth (ישוד) at moon-day”. So, also, יגודנו ,יגוד and גדוד have the same derivation. When, also, one uses such biliteral roots in the future tense Kal, it (the second letter) is not doubled. For example: יגוד he will troop, ינוד he will wander, ירום he will be high, ישוד he will devastate, ישוב he will come back. When, however, such a root is used in a reflexive sense (Hithpael) or in a causative-transitive sense the second letter is doubled Examples are: יתעודד ,יתרומם ,יתבולל ,יתגודד. Examples of the causative-transitive sense are: (Psalms 146:9) “He strengtheneth (יעודד) the fatherless and the widow”; (Isaiah 49:5) “To bring Jacob back (לשובב) to Him”; (Isaiah 48:12) “The restorer (משובב) of paths”. The form יגודנו which is used here has not the force that others will make him do something (i.e. it has not this causative-transitive sense with the direct accusative suffix נוּ) but it means “a troop will troop out from him”, exactly the same as (Jeremiah 10:20) בני יצאוני which means “my children have gone forth from me”, (as we might say “have left me”). (Cf. Rashi on Genesis דברו לשלום 37:4, and on תמלאמו Exodus 15:9.). גד גדוד יגודנו accordingly means, “troops will troop out of him” signifying that they (the Gadites) will cross the Jordan with their brethren, all armed, and remain with them until the land will have been conquered.
Alshekh
Gad will be an assailing troop. They were the advanced force in the conquest of the land.
Chizkuni
גד גדוד יגודנו, “Gad’s soldiers will troop after the armies of Israel when they go out to war (to conquer their ancestral heritage) during the battles under Joshua; they will be in the forefront as we know from Deuteronomy 3,18, where Moses commanded them to march as the vanguard of the Israelite army.
