Gen 49:19

“Through the expression "a gang of enemies" (or "a place of trial") the prophet signifies the evil Sanhedrin of the high priests and scribes, who tested the Savior with different pretenses in order to find some ground to move accusations against him and then take hold of him and execute him. But he, knowing their intentions, put them to test in his justice and delivered them to death for their sin.”

“When temptation arose, it tempted him, and he tempted them by deceiving them. Temptation is the gathering and cunning of the scribes and priests who were tempting the Lord Jesus about the tribute to Caesar, and about John's baptism, as the Scripture teaches, to whom the Lord Jesus, in his righteousness, turned the temptation back. By deceiving, that is, constantly and without any deliberation, with the intention of deceiving the tempters even more. For they said: In what authority do you do these things? He did not answer about what was asked, but he also proposed saying: I will also ask you one question: if you tell me, I will also tell you by what authority I do these things. Again they said: Is it lawful to pay taxes to Caesar, or not? He said: Why are you testing me, hypocrites? Show me the coin for the tax. And they brought him a coin, then he asked them: Whose image and inscription is this? They said to him: Caesar's. Therefore, he bound them with their own words, with their own obligation. Then he said to them: Render therefore to Caesar the things that are Caesar's, and to God the things that are God's, so that they could not come against their own words. Finally, they marveled and went away from him. But it is not surprising if he answered differently than what they expected, since he could see what was before his feet. Moses clearly explained that this prophecy of Jacob was about Christ. For he said: Blessed be he that enlarges Gad. As a lion, he rested, breaking the arms and the heads of the rulers, and saw from the beginning that the land was divided with the princes of the people. The Lord has executed justice, and judgment with Israel. Therefore, we recognize who has rested like a lion, who has broken the arms of the mighty, who has seen the divisions of those who tempt from the beginning. Therefore, there is a chasm in the earth, which swallows the slanderers, where the temptation of the treacherous is.”

“And therefore, according to a similar process, the moral sense develops: that man of ours, after confessing his error, by his repentance turns out to be converted through knowledge and shows a significant progress, so that he is tempted by the enemy and the strength of his soul and the soundness of his intentions are tested. In fact, the Scripture says, "The one who is not tempted is not credible." No one will ever reach perfection if he is not first tested in temptations.”

“(Verse 19.) Gad the robber will rob him, and he himself will rob a plant. We are interpreted according to the Hebrew. But where we put the robber, it is written Gedud (), to allude to the name Gad, which can be more significantly expressed as εὔζωνος, that is, girded or ready. But the whole story is that after fourteen years, when Reuben and half of the tribe of Manasseh had returned to the sons whom he had sent across the Jordan to take possession, he found a great war against the neighboring peoples, and after defeating the enemy, he fought bravely. Read the book of Joshua (Joshua 13) and Chronicles (1, 5). I am aware that there are more mysteries in the blessings of the patriarchs, but they are not relevant to the current work.”

“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. והוא יגד עקב means all his troops will return in their own tracks back to their territory which they will receive on the other side of the Jordan and not one of them will be missing. עקב This means: By the same roads and paths upon which they had traveled shall they return. The word עקב has the same meaning as in (Psalms 128:20) “And thy foot-steps (עקבותיך) were not known”; (Song of Songs 1:8) “by the footsteps (עקבות) of the flock”. In old French traces; English, tracks.”

“‘GAD G’DUD Y’GUDENU.’ Rashi, in accordance with Onkelos, explained it as follows: A troop will troop out of him, and that troop will troop back upon its footsteps, meaning it will return in its own track back to its territory in peace [and not one of them will be missing]. The correct interpretation [appears to be that the word y’gudenu here] is as in the verse: When he cometh up against the people that he invadeth (‘y’gudenu’). The verse is thus stating that a troop will always assail Gad, that he will have many wars, with enemy troops spreading out over his land, and that he will follow the enemy in his track and be victorious over him and pursue him, returning on the heel of those who shame them. Jacob thus praised the Gadites for their valor and for their victory over all those who enter into battle against them. This is similar to the blessing which Moses our teacher gave them, as it is said, Blessed be He that enlargeth Gad; he dwelleth as a lioness. Since Gad inherited a very wide and large land which was across the Jordan, bands from Ammon and Moab, his evil neighbors, would always descend upon him, claiming the land and invading it. Yet Gad lurked like a lioness over its prey, fearing not their noise, nor showing any dismay at their shouting. This fitting interpretation I learned from the Jerusalem Talmud, where in Tractate Sotah they say: “Gad g’dud y’gudenu, a troop will come trooping upon him, but he shall troop upon it;” that is to say, bands will come to gather wealth and assail him, but he shall troop upon them and bring his troops into their land. Perhaps the prophet Jacob was alluding to the war of Jephthah the Gileadite against the children of Ammon, as the children of Gad inherited all the cities of Gilead, and half of the land of the children of Ammon. The children of Ammon were always warring against the men of Gilead, and Jephthah scarcely passed over them and he smote them and their cities [with] a very great slaughter. This event was indeed a great miracle, and so the prophet Jacob mentioned it, even as he mentioned the matter of Samson.”
