Numbers 2:5

And those that do pitch next unto him [shall be] the tribe of Issachar,.... Who with Zebulun, after mentioned, as placed with him under the same standard, were the brethren of Judah, by the same mother Leah, and so fitly put together, as most likely to continue in harmony and love; and being the youngest sons of Leah, and brethren of Judah, would, without any reluctance or murmuring, pitch under their elder brother's standard:

and Nethaneel, the son of Zuar, [shall be] captain of the children of Issachar; see Numbers 1:8.
