וַתֹּ֣אמֶר אֶל־הָעֶ֗בֶד מִֽי־הָאִ֤ישׁ הַלָּזֶה֙ הַהֹלֵ֤ךְ בַּשָּׂדֶה֙ לִקְרָאתֵ֔נוּ וַיֹּ֥אמֶר הָעֶ֖בֶד ה֣וּא אֲדֹנִ֑י וַתִּקַּ֥ח הַצָּעִ֖יף וַתִּתְכָּֽס׃
Lalu ia bertanya kepada hamba itu, “Siapakah laki-laki di sana itu, yang berjalan di padang menyongsong kita?” Jawab hamba itu, “Dialah tuanku.” Maka Ribka mengambil kerudungnya, lalu menyelubungi dirinya.
Rashi
ותתכס AND [SHE] COVERED HERSELF — This has a passive meaning (she was covered); it is like (35:8) ותקבר “and she was buried”, and (1 Samuel 4:18) ותשבר “and [his neck] was broken”.
Rashbam
?מי האיש הלזה ההולך בשדה לקראתנו, this verse raises a number of questions. Did Rivkah enquire about the identity of every man that they encountered on this journey? Furthermore, why did the Torah have to write the words בשדה לקראתנו, “in the field toward us?” It appears that the verse is somewhat abbreviated. What Rivkah wanted to know was why the man approaching them had detoured from the regular path and was coming across the field in their direction.
Sforno
ותתכס, for she was afraid to look more closely, similar to Moses being afraid to look more closely at the burning bush in Exodus 3,6.
