The meaning of young in the bible is interesting considering when Paul is talking about Timothy in 1 Timothy 4:12, NIV: “Don’t let anyone look down on you because you are young, but set an example for the believers in speech, in conduct, in love, in faith and in purity.” Timothy was around 37 years of age.
