Rashi on Genesis 22:3/רש"י על בראשית כ״ב:ג׳

1וישכם AND HE ROSE EARLY — He was alert to fulfil the command (Pesachim 4a)

2ויחבוש AND HE SADDLED [HIS ASS]—He himself: he did not order one of his servants to do so, for love disregards the rule imposed on one by his exalted position in life. (“Love” here means Love of God as displayed in obedience to His command.) (Genesis Rabbah 55:8)

3את שני נעריו HIS TWO LADS — Ishmael and Eliezer. For a man of high standing should not travel without two men as attendants (Leviticus Rabbah 26:7) so that if one needs to ease himself and goes aside for this purpose the other will still remain with him (Midrash Tanchuma, Balak 8)

4ויבקע AND HE CLEAVED [THE WOOD] — Its rendering in the Targum וצלח has the same meaning as the verb in (2 Samuel 19:18) And they rushed into the Jordan”, which signifies cleaving the waters; old French fendre; English to split.
