וְתֵרֶ֤א אֹיַ֙בְתִּי֙ וּתְכַסֶּ֣הָ בוּשָׁ֔ה הָאֹמְרָ֣ה אֵלַ֔י אַיּ֖וֹ יְהוָ֣ה אֱלֹהָ֑יִךְ עֵינַי֙ תִּרְאֶ֣ינָּה בָּ֔הּ עַתָּ֛ה תִּֽהְיֶ֥ה לְמִרְמָ֖ס כְּטִ֥יט חוּצֽוֹת׃
Mon ennemie en sera témoin et sera couverte de honte, elle qui me dit: "Où est l’Éternel, ton Dieu? " Mes yeux se repaîtront de sa vue; déjà je la vois foulée aux pieds comme la boue des rues.
Rashbam
כסות עינים, they will not be able to look at you as someone who had been discredited. We find the word כסה used in a similar sense in Exodus 10,5 וכסה את עין הארץ, “it (the locust) will cover the visible part of the earth, i.e. the earth will not be “naked,” “exposed.” A similar sequence appears in this sense in Ezekiel 28,17 לראוה בך, “so that they may gaze upon,” (not turn away in shame and disgust). The expression also occurs in a similar sense in Micah 7,10 עיני תראינה בה, “my eyes shall behold her.”
Rabbeinu Bahya
ואמר אי אלוהימו, “and when he (the enemy) will say (sarcastically) where is their god?” We know that Titus after cutting into the dividing curtain in the Temple found the Holy of Holies empty, exclaimed in this fashion, astounded that there was no image (compare Gittin 56b). This is also what the prophet Micah 7,10 referred to when he said: “when my enemy sees it, she will be covered with shame. She who taunts me with ‘where is He, the Lord your G’d?’”
Radak
ליחמנה במקלות, to bring them to heat through their viewing the sticks, as I already explained. The letter ה at the end of the word ליחמנה is appended just as we find this letter appended in such words as אותנה (Exodus 35,26), where we do not know any reason for this addition. The word really should have been ליחמן without the letter ה at the end but with a dagesh in the final ן. Still we do have a similar construction to ours here in Micah 7,7 עיני תיראנה בה as well as in Ezekiel 4,12 תעגנה לעיניהם where the letter נ in תעגנה is “weak,” i.e. without the dagesh we would have expected. Even though, as we explained, the places where these constructions occur are not quite analogous to one another, the fact remains that the entire story is told by the Torah in such detail in order to show the reader to what extent G’d’s providence intervened in order to make sure that Yaakov did not lose out to the crooked Lavan. This once again confirms what we read in Psalms 37,12 and 33 that זומם רשע לצדיק....ה' לא יעזבנו בידו, “when the wicked tries to set a trap the righteous G’d will not abandon the righteous to the devices of the wicked.”
Rashi
(37) ואמר אי אלהימו AND HE SAYS WHERE IS THEIR GOD — i.e., when the enemy (cf. this with Rashi’s previous explanation) will say, “Where is the God of Israel?” — even as Titus, the wicked, asked, when he pierced the curtain of the Holy of Holies (cf. Gittin 56b), just as it is said, (Micah 7:10) “Then my enemy shall see it, and shame shall cover her who said unto Me, Where is the Lord, thy God?”
