An interesting aspect of Jesus’ kingdom-sayings and parables in Luke is that none of them make any reference to the great Jewish symbols – none of the parables/sayings are tied to the land, or Torah, or nationalistic hope of liberation. Jesus has redefined the kingdom (Luke is full of redefinitions – the most prominent ones being the redefinition of the family and the people of God) away from the traditional symbols and the hope of national vindication , and by way of odd little sayings and parables, shows and tells that not only is the kingdom at hand and the end of the exile near but is happening through his own work.
‘Repentance’, in a good many texts, was what Israel must do if her exile is to come to an end. Though the Greek word metanoia and its cognates, which occur in the gospels with this meaning, are rare in the Septuagint – and when they do occur, they refer, more often than not, to YHWH himself ‘repenting’ – the first-century sense of the word encapsulates a range of meanings expressed in other ways in the Hebrew scriptures and their Greek translations. Deuteronomy spoke of Israel ‘returning’ to YHWH with her whole heart; this would be the condition of her forgiveness and of the return from exile. In Deuteronomic terms, this would mean a return to the shema, to the love of YHWH alone with all the heart. The prophets regularly used the term ‘repent’ to denote the turning to YHWH which would result in restoaration, return from exile. Indeed, the word shub and epistrephein, since they mean ‘return’, hint constantly, particularly in Jeremiah, that for Israel to ‘return’ to YHWH with all her heart is the crucial thing that will enable her to ‘return’ to her own land. The whole point of passages like Daniel 9, Ezra 9 or Nehemiah 9 is that these great prayers of repentance – and we must be careful not to confine our thinking simply to occurrences of shub and epistrephein – are prayers precisely designed to bring about the return from exile. (We may note once again that all three books are clearly ‘post-exilic’ in the normal sense, and yet still seeking the real ‘return’.) (N.T. Wright, ‘Jesus and the Victory of God’, pp. 248-249)
