Where did the tribes camp in relation to the dwelling place?

Answer From The Annual Reading Schedule - Week 31 Notes For Numbers: See the below table created with data from Numbers 2 and 3 and the note below it:

The numbers for the Lewites (Levites) do not add up correctly in Numbers 3. The mis-match is as follows:

The Gereshonites – 7,500 (Numbers 3:21-22)
+ The Qehathites – 8,600 (Numbers 3:27-28)
+ The Clans of Merari – 6,200 (Numbers 3:33-34)
SHOULD EQUAL = 22,300

The total based upon the numbers given should equal 22,300. However, Numbers 3:39 just says the total was 22,000. Why the difference?

Well, it is possible that someone along the way has misunderstood the Hebrew letters representing numbers in the original scrolls. Some Hebrew letters look very similar and could be mistaken for each other.

In fact, it appears that may have been exactly what happened. What evidence do we have for this? We must look at Brenton's English translation of the Greek Septuagint. The Septuagint is the Greek Translation of the Tanakh (or commonly called “Old Testament”). In Brenton's English translation of this Greek document, which was written more than 2,000 years ago and is older than the Hebrew most translations use, we see in Numbers 3:34 it says:

The mustering of them according to number, every male from a month old and upwards, was six thousand and fifty.

The English translations using the Hebrew say 6,200, while this English translation of the Greek says 6,050. However, that still leaves us at 22,150 in the Greek. The Greek total in Numbers 3:39 also says 22,000 according to Brenton's translation. That's closer, only 150 off the mark, but still something is amiss. This at least, however, does give evidence that the Hebrew letters in the original manuscript may be easily misunderstood by those copying or translating from the original Scroll.

There are other explanations by learned men on the Internet, but I do not feel it is necessary to share those in these notes as I cannot verify whose explanation would be correct since I am not a language or manuscript expert.
