Infidel

Hastings' Dictionary of the Bible

INFIDEL . This word has more force now than formerly. In AV [Note: Authorized Version.] it signifies no more than ‘unbeliever.’ It occurs in 2 Corinthians 6:15 , 1 Timothy 5:8 (RV [Note: Revised Version.] ‘unbeliever’ in both). So ‘infidelity’ in 2Es 7:44 is simply ‘unbelief’ (Lat. incredulitas ).
