Whose names are these: Of Ruben, Elisur the son of Sedeur.

These are the names of those who are to be your helpers: from Reuben, Elizur, the son of Shedeur;

the names of whom are these: of Ruben, Elizur the son of Shedeur;

Haec sunt autem nomima virorum qui stabunt vobiscum: de Ruben, Elisur, filius Sedeur.

The princes of the tribes, selected Numbers 1:4 under divine direction, were for the most part the same persons as those chosen a few months previously at the counsel of Jethro Exodus 18:21-26. Nahshon, prince of Judah, is mentioned in Exodus 6:23, and Elishama, in 1-Chronicles 7:26-27. The peers of men like these were no doubt entitled, among their fellows, to the epithet "renowned," Numbers 1:16.

And these [are] the names of the men that shall (d) stand with you: of [the tribe of] Reuben; Elizur the son of Shedeur.
(d) And afflict you when you number the people.

And these are the names of the men that shall stand with you,.... Be present with Moses and Aaron when numbering the people; not merely as spectators of the affair, and inspectors of the accounts, but as assistants in the work; each man in his tribe, being best acquainted with the families and houses in it; and these men were not pitched upon by Moses and Aaron, nor chosen by their respective tribes, but were appointed and named by the Lord himself, which was doing them great honour:
of the tribe of Reuben: or "for Reuben" (c), for the taking the number of men in this tribe; and so of all the rest, see Numbers 1:44,
Elizur the son of Shedeur; from Numbers 1:5 the names of those several men are given, which were very proper for Moses and Aaron to know, though of little importance to us; nor the signification of their several names, given by Ainsworth and others; only, as Bishop Patrick observes, most of them show how much God was in the thoughts of those who, imposed these names on their children, several of them having in them "El" or "Eli", "God" or "my God", and "Shaddai", "Almighty" or "all-sufficient": to which may be added, that in some of them they seem to respect the Messiah, as Elizur, signifying "my God the rock"; and Shelumiel may be rendered, "God my peace"; and Zurishaddai, "my rock the Almighty", or "all-sufficient"; and Pedazhur, "the rock redeemeth": nor is there anything of any moment to be remarked, unless the order in which the several tribes are placed; and first the children of Leah, beginning with Reuben, the firstborn; and the rest, Simeon and Judah, are ranked according to their birth; Levi being omitted, because that tribe was not now numbered, and besides, Moses and Aaron were of it; and then Issachar and Zebulun; after those the children of Rachel, because of her honour and glory above the handmaids, as Aben Ezra remarks; who further observes, that it begins with Ephraim, following Jacob our father, that is, because of the blessing of Jacob, who preferred Ephraim the younger to Manasseh the elder; and here Ephraim and Manasseh are set before Benjamin, because they were in the place of Joseph; and after that the account goes on with Daniel, because, he was the firstborn of the handmaids; and after him Asher, though the second son of Zilpah, is placed before Gad, the first son, because, says the same Aben Ezra, the Lord knew that he would be the head of those that encamped by the standard of Daniel, and so is placed next to him; and after him Gad, who was the firstborn of Leah's handmaid; and Naphtali last of all, the second son of Bilhah: this order seems to be designed to suit with their encampments, and the form of them.

these are the names of the men that shall stand with you, &c.--Each is designated by adding the name of the ancestors of his tribe, the people of which were called "Beni-Reuben," "Beni-Levi," sons of Reuben, sons of Levi, according to the custom of the Arabs still, as well as other nations which are divided into clans, as the Macs of Scotland, the Aps of Wales, and the O's and the Fitzes of Ireland [CHALMERS].

Reuben - The tribes are here numbered according to the order or quality of their birth, first the children of Leah, then of Rachel, and then of the handmaids.
