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
Sons of man The sons of Abraham, Isaac, and Jacob, who are called man. About Abraham it is stated (in Gen. 20:7): “Restore the man’s wife.” About Isaac it is stated (ibid. 24:65): “Who is that man...?” About Jacob, it is stated (ibid. 25:27): “and Jacob was a plain man.”
Rashbam
הלזה; whenever the word הלזה is mentioned it refers to someone or something that one sees from afar, indistinctly. For instance in Genesis 24,65 Rivkah asked Eliezer who the man was who was approaching them from a distance. The word הזה, on the other hand, refers to someone or something close at hand, as for instance Haman in Esther 7,6, to whom Esther points when the King asked here who the culprit was who wanted to destroy her and her people.
Radak
לפנות ערב, at the time when the sun turns down towards the horizon. This is the time of day when many people go for a walk among the shrubs and bushes. While he was thus walking, he raised his eyes looking further along the route he was walking on and he saw גמלים באים, and he veered off his path to walk toward them to check if this was Avraham’s servant Eliezer who was walking at the head. This is what Rivkah meant when she referred to the man who was walking לקראתנו, (verse 65). ותשא, she thought that possibly the man approaching might be Yitzchok; this is why she asked the servant, to find out if her assumption was correct.
