וַתֹּ֥אמֶר לֵאָ֖ה בגד [בָּ֣א] [גָ֑ד] וַתִּקְרָ֥א אֶת־שְׁמ֖וֹ גָּֽד׃
האָט לאה געזאָגט: מזל איז געקומען; און זי האָט גערופֿן זײַן נאָמען גָד.
Rashi
and an army of broken people fall by his signals Heb. חלכאם, an army of broken people. I saw in the great masorah that חלכאים is one of fifteen words that are written as one word and read as two words, as is בגד in the verse (Gen. 30:11) commencing “And Leah said.” Also (in Deut. 33:2), “a fiery Law (אשדת) is to them”; (Isa. 3: 15), “What do you mean (מלכם) that you crush My people?” Also this word means חל כאים, an army of broken people. כאים is an expression of (below 109:16) “and a broken-hearted one (ונכאה לבב) to kill.” If you say that the “nun” is the radical, (Ezek. 13:22) “Because you have broken (הכאות) the heart of the righteous” will prove that [it is not]. We learn that the “nun” of נראה is like the “nun” of (I Sam. 15:9) נמבזה and the “nun” of (Jer. 6:14) נקלה, and so is its interpretation: and...fall by the signals of this wicked man, with his hints and his winks, an expression of (Isa. 41:21) “present your signals (עצמותיכם).” and (ibid. 33:15) “and closes (ועצם) his eyes,” an army of poor people. Another explanation: בעצומיו, by his mighty men. Said Rabbi Simon: This wicked man puts into his “callirus,” meaning army, only mighty men like himself, as it is said (in Dan. 3:20): “And he commanded the mighty warriors who were in his army to bind Shadrach, Meshach and Abed- nego” (Mid. Ps. 10:5). However, Menachem, (p. 89) interprets חלכאים as “poor and weak (וחלך),” the “chaf” being a radical.
Ibn Ezra
לגד For the host of the heavens.10A. V., That troop. R. Moses Hakkohen says, that גד means the planet Jupiter which forebodes only good things;11According to the belief of Eastern people; In Arabic, Jupiter is called السعد الاكبر the greatest fortune. that in Arabic the word has the same meaning;12جَدٌ Felicitas. but that בגל (Gen. 30:11) is different from it.13I. E. renders בגד a troop comes, and refers it to the troop of five children, which Leah then had.

A small cake first. There is a Midrash Aggdah in Bereishis Rabboh9The Midrash cited by Rashi is not found in our texts of Midrash Rabboh on this verse. (why he wanted it first) on [the verse], “And Leah said, ‘Unexpected success has come.’”10Bereishis 30:11.
