Numbers 4:7

And upon the table of shewbread they shall spread a cloth of blue,.... That that also might not be seen nor touched by the Levites:

and put thereon the dishes, and the spoons, and the bowls, and the covers to cover withal: all which belonged to the shewbread table; the use of which, Exodus 25:29; these seem to be put not immediately upon the table, but upon the blue cloth spread over the table:

and the continual bread shall be thereon: the shewbread is called "continual", because it was always on the table; for while the one was removing by a set of priests, which had stood a week, new loaves were placed by another set of priests: this bread seems at this time to be placed also upon the table, spread with the blue cloth; and from hence it appears, that the Israelites had the shewbread in the wilderness; for the making of which they might be supplied with corn from the neighbouring countries, though they themselves needed not any, being daily fed with manna.
