4. Mose 4:17

In order to prevent as far as possible any calamity from befalling the Levites while carrying the most holy things, the priests are again urged by the command of God to do what has already been described in detail in Num 4:5-15, lest through any carelessness on their part they should cut off the tribe of the families of the Kohathites, i.e., should cause their destruction; viz., if they should approach the holy things before they had been wrapped up by Aaron and his sons in the manner prescribed and handed over to them to carry. If the Kohathites should come for only a single moment to look at the holy things, they would die. אל־תּכריתוּ, "cut ye not off," i.e., "take care that the Kohathites are not cut off through your mistake and negligence" (Ros.). "The tribe of the families of the Kohathites:" shebet, the tribe, is not used here, as it frequently is, in its derivative sense of tribe (Tribus), but in the original literal sense of stirps.

In the former chapter an account was taken of the whole tribe of Levi, in this we have an account of those of that tribe who were in the prime of their time for service, betwixt thirty and fifty years old. I. The serviceable men of the Kohathites are ordered to be numbered, and their charges are given them (v. 2-20). II. Of the Gershonites (Num 4:24-28). III. Of the Merarites (Num 4:29-33). IV. The numbers of each, and the sum total at last, are recorded (Num 4:34, etc.).
