Numbers 24:1

he went not, as at the other times, to meet with omens] The Heb. has a curious idiom which may be rendered either as in R.V., or -as at other times" (omitting -the"), i.e. as was his usual practice on similar occasions. In either case the verse cannot be from the same writer as that of ch. 23, for on the one hand ch. 23 does not relate that Balaam sought for omens, and on the other (if the present words refer to his usual practice) the remark that he did not seek for omens would more naturally have been placed at the beginning of ch. 23 and not after two of his utterances.
