Charles Ellicott Commentary Numbers 4:7

"And upon the table of showbread they shall spread a cloth of blue, and put thereon the dishes, and the spoons, and the bowls and the cups wherewith to pour out; and the continual bread shall be thereon:" — Numbers 4:7 (ASV)

And covers to cover with. —Better, and the cups for the drink-offering (or libation).

And the continual bread. —The shew-bread is so called because it was renewed every Sabbath day, and was continually before the face of the Lord even (as it appears from this verse) during the marches of the Israelites through the desert (Exodus 25:30; Leviticus 24:5).
