ציטירנדיקער פּירוש אויף בראשית 29:9

באה עם הצאן IS COMING WITH THE FLOCK — The accent in the word באה is on the א, and the Targum is אתיא (a participle), “she is coming”; but in (v. 9) “And Rachel came (באה)”, the accent is on the first syllable, on the ב, and the Targum is אתת, “she came”. The former expresses the meaning “she is doing something” (a participle), the latter expresses the meaning “she has done something’ (a past tense).

Tanchuma Balak 5 quotes Proverbs 28,10: “he who misleads the upright into an evil course will fall into his own pit, but the blameless will prosper,” as applying to our situation. According to the Midrash, in earlier times people observed sexual mores, respecting laws laid down by G’d. They base this on Genesis 29,9 “and Rachel came with the flocks which belonged to her father.” [Her father did not need to worry that the male shepherds would molest her. Ed.]. We have a similar statement concerning the seven daughters of Yitro who were not scared of encountering male shepherds when watering their father’s flocks (Exodus 2,16). Then there arose Bileam who misled people into practicing sexual permissiveness. He would therefore fall victim to being misled himself. This is the reason G’d asked him the question: “who are these men with you?” Bileam jumped to the conclusion that there are times when G’d can be deceived and decided to accept the mission to curse the Jewish people looking for a point in time when G’d’s “blind side” would be turned in his direction.

'והנה תנור עשן וגו BEHOLD A SMOKING FURNACE — He foreshadowed to him that these Monarchies would descend into Gehinom (Pirkei DeRabbi Eliezer 28).

באה IT (SHE) CAME — The accent is on the first syllable, consequently it must signify that it (the sun) had already set. If, however, the accent were on the last syllable, on the א, it would signify that there was darkness whilst it was setting (i. e. the former is a perfect, the latter a participle). It is impossible to explain it thus here (that it means the sun was setting) because it has already been stated (v. 12) “And it came to pass that when the sun was setting”, and the passing of the smoking furnace took place after this — consequently the sun had set already when it passed. This is the difference in the case of every word (verb), feminine gender, whose root has two letters, as בא ,קם ,שב: when the accent is on the first syllable, it is the perfect tense, as is this word באה here, and like (19:9) “And Rachel (באה) came”; (37:7) “And my sheaf קמה arose”; (Ruth 1:15) “Behold, thy sister-in-law (שבה) has gone back”; but when the accent is on the last syllable it is a present tense (participle), denoting an action being done now and continuing to be done, as for instance, (29:6) “She is coming (באה) with the sheep”; (Ester 2:14) “In the evening she used to come (באה) and in the morning (שבה) she used to return”.
