Because there fell wrath - literally, “And there fell wrath.” The falling of God’s wrath was not the cause of Joab’s ceasing. His motive is clearly stated in 1 Chronicles 21:6. See also the marginal references.
Neither was the number ... - The meaning is, that in the portion of the chronicles of King David which treated of numbers - the number of the standing army, of the Levitical and priestly courses, the singers, etc. - the return of the number of the people made by Joab was not entered. The disastrous circumstances which followed on the taking of the census perhaps produced a feeling that God might he further provoked by its being put on record in the state archives. The numbers which have come down to us must therefore have been derived from private sources.
