Gen 22:3

“Abraham arose in the morning (because the text adds "in the morning," perhaps it wished to show that the beginning of light shone in his heart), saddled his ass, prepared wood, took along his son. He does not deliberate, he does not reconsider, he does not take counsel with any man, but immediately he sets out on the journey."And he came," the text says, "to the place which the Lord had said to him, on the third day." I omit now what mystery the "third day" contains. I consider the wisdom and intention of the one who tests him. Since everything was done in the mountains, was there thus no mountain nearby. But a journey is prolonged for three days, and during the whole three days the parent's heart is tormented with recurring anxieties, so that the father might consider the son in this whole lengthy period, that he might partake of food with him, that the child might weigh in his father's embraces for so many nights, might cling to his breast, might lie in his bosom? Behold to what an extent the test is heaped up.”

“(Verse 3) And he went to the place which God had told him about, on the third day. It should be noted that from Gerar to Mount Moriah, that is, the site of the temple, is a three-day journey, and consequently it is said that he arrived there on the third day. Therefore, some people mistakenly think that Abraham lived at the oak tree in Mamre during that time, when in fact the journey from there to Mount Moriah is barely a full day's journey.”

“וישכם AND HE ROSE EARLY — He was alert to fulfil the command (Pesachim 4a) ויחבוש 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) את 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) ויבקע 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.”

“AND HE CLEAVED THE WOOD FOR THE BURNT-OFFERING. This illustrates Abraham’s zeal in performing a commandment for he thought that perhaps there would be no wood in that place, and so he carried it for three days. It may be that Abraham disqualified for use as an offering any wood in which a worm is found, as is the law of the Torah, and so he took from his house sound wood for the burnt-offering. Hence it says, And he cleaved the wood for the burnt-offering.”
