1 Timothy 1:13 in the King James Version
Who was before a blasphemer, and a persecutor, and injurious: but I obtained mercy, because I did it ignorantly in unbelief.
Context
12 I thank him who enabled me, Christ Jesus our Lord, because he counted me faithful, appointing me to service,
13 although I used to be a blasphemer, a persecutor, and insolent. However, I obtained mercy because I did it ignorantly in unbelief.
14 The grace of our Lord abounded exceedingly with faith and love which is in Christ Jesus.
