And Jehovah said to Moses, They shall present their offering for the dedication of the altar, each prince on his day.

And Jehovah saith unto Moses, 'One prince a day, one prince a day, do they bring near their offering for the dedication of the altar.'

And the Lord said to Moses, Let every chief on his day give his offering to make the altar holy.

And the Lord said to Moses: "Let each of the leaders, on each of the days, offer their gifts for the dedication of the altar."

And the Lord said unto Moses,.... For before this was said to him, even what follows, Moses knew not, as the same writer observes, how they should offer, in what order, whether according to their birth, or whether according to the journeying of their camps, or whether they should offer together, or one after another, one day after another (g); this affair is set in a clear light:
they shall offer their offering each prince on his day; one on one day, and the other on the next, and so on successively for twelve days running; and this was ordered for the greater solemnity of the service, and that it might be taken notice of, and each have the honour and credit of it; and this was done, not according to the order of their birth, but as their standards were fixed, first Judah, and those under him, and so the rest in course:
for the dedicating of the altar; see Numbers 7:10.
(g) Vid. Siphri apud Yalkut in loc.

They shall offer . . . each prince on his day, &c.--Eastern princes were accustomed anciently, as they are in Persia still on a certain yearly festival, to sit upon their thrones in great state, when the princes and nobles, from all parts of their dominions, appear before them with tributary presents, which form a large proportion of their royal revenue. And in the offering of all gifts or presents to great personages, every article is presented singly and with ostentatious display. The tabernacle being the palace of their great King, as well as the sanctuary of their God, the princes of Israel may be viewed, on the occasion under notice, as presenting their tributary offerings, and in the same manner of successive detail, which accords with the immemorial usages of the East. A day was set apart for each, as much for the imposing solemnity and splendor of the ceremony, as for the prevention of disorder and hurry; and it is observable that, in the order of offering, regard was paid to priority not of birth, but of rank and dignity as they were ranked in the camp--beginning at the east, proceeding to the south, then to the west, and closing with the north, according to the course of the sun.

On his day - And in this offering they followed the order of their camp, and not of their birth.
