One spoon - כף caph, a censer, on which they put the incense. See Exodus 25:29. It is worthy of remark that the different tribes are represented here as bringing their offerings precisely in the same order in which they encamped about the tabernacle. See Numbers 2 and Numbers 10.

Numbers 1:9 Of Zebulun; Eliab the son of Helon.

Numbers 2:7 Then the tribe of Zebulun: and Eliab the son of Helon shall be captain of the children of Zebulun.

Beginning with a census of the men of war (i.) and the order of the camp (ii.), it devotes specific attention to the Levites, their numbers and duties (iii., iv.). Then follow laws for the exclusion of the unclean, v. 1-4, for determining the manner and amount of restitution …
