Genesis 22:3

And Abraham rose up early in the morning,.... For it seems it was in a dream or vision of the night that the above orders were given; and as soon as it was morning he rose and prepared to execute them with all readiness, and without any hesitation and delay:

and saddled his ass; for his journey, not to carry the wood and provision on, which probably were carried by his servants, but to ride on; and this Jarchi thinks he did himself, and the words in their precise sense suggest this; but it does no, necessarily follow, because he may be said to do what he ordered his servant to do; of the Jews' fabulous account of this ass, see Zechariah 9:9:

and took two of his young men with him; the Targum of Jonathan says, these were Ishmael his son, and Eliezer his servant; and so other Jewish writers r, who tell us, that just at this time Ishmael came out of the wilderness to visit his father, and he took him with him; but for this there is no foundation: they were two of his servants, of whom he had many:

and Isaac his son: who was the principal person to be taken, since he was to be the sacrifice: whether Abraham acquainted Sarah with the affairs and she consented to it, cannot be said with certainty; it is plain Isaac knew not what his father's design was; and though Sarah and the whole family might know, by the preparation made, he was going to offer a sacrifice, yet they knew not where, nor what it was to be;

and clave the wood for the burnt offering; not knowing whether he should find wood sufficient on the mountain, where he was to go; and that he might not be unprovided when he came there, takes this method, which shows his full intention to obey the divine command:

and rose up, and went unto the place of which God had told him; that is, he mounted his ass, and rode towards the place God had spoken of to him, and who had directed him which way to steer his course.
