Moses said, we will go with our young and with our old,.... The latter were necessary to guide, direct, and instruct in the business of sacrifice, and to perform it as heads of their respective families; and the former were to be present, that they might be trained up and inured to such religious services: with our sons and with our daughters; as with persons of every age, so of every sex, who had all a concern herein, especially as it was a solemn feast, which all were to partake of: with our flocks and with our herds will we go; which were requisite for the sacrifices, not knowing which they were to sacrifice, and with which to serve God, till they came to the place where they were to sacrifice; see Exo 10:26, for we must hold a feast unto the Lord; which required the presence of old and young, men, women, and children, to join in it, and their flocks and their herds, out of which it was to be made.
