וַיַּשְׁכֵּ֨ם אַבְרָהָ֜ם בַּבֹּ֗קֶר וַֽיַּחֲבֹשׁ֙ אֶת־חֲמֹר֔וֹ וַיִּקַּ֞ח אֶת־שְׁנֵ֤י נְעָרָיו֙ אִתּ֔וֹ וְאֵ֖ת יִצְחָ֣ק בְּנ֑וֹ וַיְבַקַּע֙ עֲצֵ֣י עֹלָ֔ה וַיָּ֣קָם וַיֵּ֔לֶךְ אֶל־הַמָּק֖וֹם אֲשֶׁר־אָֽמַר־ל֥וֹ הָאֱלֹהִֽים׃
И встал Авраам рано утром, оседлал задницу свою и взял с собою двух своих юношей и Исаака, сына его; и отколол дрова для всесожжения, и встал, и пошел к месту, о котором сказал ему Бог.
Rashi
וישכם AND HE ROSE EARLY — He was alert to fulfil the command (Pesachim 4a)
Bekhor Shor
Avraham awoke early in the morning: To saddle his donkey, as he was alacritous and driven to do the will of his Maker.
Chizkuni
ויקח את שני נעריו, “he took his two attendants;” here Rashi does not interpret what he had explained in connection with a similar expression when Bileam took his two servants (Numbers 22,22). There he had explained that prominent people must always travel in the company of two attendants so that one of them has to follow a call of nature so the prominent person will not have been left alone.
