Exodus 36:3

And they received of Moses all the offering
That is, Bezaleel and Aholiab received it of him, who delivered it to the several workmen, as the nature of their work required, some one thing, and some another: to some gold, to others silver, to others brass, and to some they delivered out fine linen, and blue, purple, and scarlet yarn, and to others shittim wood; Moses gave all out faithfully that he received, and kept back nothing for his own use or private advantage, even all the above things of which the offering consisted:

which the children of Israel had brought for the work of the
service of the sanctuary, to make it [withal];
and which perhaps they went and fetched the same day they were called together, and acquainted with the mind of God concerning it; or at least they brought it in a very short space of time, and as soon as it possibly could be; it was delivered to the workmen, that the work might be begun, and carried on with the utmost expedition:

and they brought yet unto him free offerings every morning;
they continued for a course of time afterwards to bring their freewill offerings of one thing or another to Moses, every morning, which perhaps was the most suitable time for him to receive them; and best expresses their readiness and diligence in bringing them, and which, as they brought, he sent to the workmen, as appears by what follows.
