But in our contemporary context, the challenge to understanding this key teaching of Jesus comes from an entirely other direction. But centre of Jesus’ teaching is the proclamation of the kingdom—even the most sceptical NT scholar has agreed that his teaching in Mark 1.15 belongs to the historical core of what Jesus said and taught. We might then look at surrounding culture—how was the word used in Greek and Roman culture? Keener puts his finger on a key question: how was this term used in the Greek Old Testament, the Septuagint (referred to as ‘LXX’). I have a print lexicon (Abbott Smith) which gives exactly this information: what Hebrew word does this Greek word translate.
