Where does it talk about numbered days in the bible?

Answer 1

Where the word "numbered" is used in the KJV... no reference is made to one's "days"; but, among other things, of the "hairs on one's head."

"...the very hairs of your head are all numbered." (Matt.10:30)

In Job 14, however... there's a passage that some might construe as our days being numbered... although it's not worded that way:

"Man's days are determined; you have decreed the number of his months and have set limits he cannot exceed. So look away from him and let him alone, till he has put in his time like a hired man." (Job 14:5-6 NIV)
