2 Kings 15:13

Shallum king of Israel. He is slain, after a month, by Menahem (Not in Chronicles)

13. a full month R.V. the space of a month. The margin of A.V. gives, -Heb. a month of days". The rendering of R.V. corresponds with that of A.V. in Genesis 29:7 for the same words. The Hebrew for -of days" is added adverbially, as we use -time" in such phrases as -in a month's time" = -in a month" -in a year's time" &c.
