Numbers 1:20

1:20 And they were as follows:

The descendants of Reuben, the firstborn son of Israel: According to the records of their clans and families, all the males twenty years old or older who could serve in the army were listed by name individually.

Numbers 1:22

1:22 From the descendants of Simeon: According to the records of their clans and families, all the males numbered of them ¹  twenty years old or older who could serve in the army were listed by name individually.

Numbers 3:39

3:39 All who were numbered of the Levites, whom Moses and Aaron numbered by the word ²  of the Lord, according to their families, every male from a month old and upward, were 22,000. ³ 

¹ tc Some witnesses have omitted “those that were numbered of them,” to preserve the literary pattern of the text. The omission is supported by the absence of the expression in the Greek as well as in some MT mss. Most modern commentators follow this.

¹ tn Here again the Hebrew has “at the mouth of,” meaning in accordance with what the Lord said. So also in v. 51.

² tn The total is a rounded off number; it does not duplicate the precise total of 22,300. Some modern scholars try to explain it by positing an error in v. 28, suggesting that “six” should be read as “three” (שֵׁשׁ [shesh] as שָׁלֹשׁ [shalosh]).
