How many died because of immorality in the wilderness? Why does 1 Corinthians 10:8 say that 23,000 Israelites fell in one day for committing fornication, while Numbers 25:9 gives the figure as 24,000?

1 Cor 10:8 NWT


  Neither let us practice sexual immorality, as some of them committed sexual immorality, only to fall, 23,000 of them in one day.


Num 25:9 NWT


  Those who died from the scourge amounted to 24,000.
1) It is possible, that those that died that very day amounted to 23000 and those that died in the following day(s) added 1000 more. 

2) It could have been Paul not remembering the exact number.

Because of my belief in the inspiration and inerrancy, I believe the 1st.
