<p>10:19- see on Dt. 7:4.</p><p><i>But I say: Did Israel not know? First Moses said: I will provoke you to jealousy with those who are no nation, with a nation void of understanding will I anger you-</i> Paul sees the Jewish anger at Gentile conversion to Christ as a reflection of their jealousy. If Gentiles became followers of some idol cult, the Jews would have been indifferent. But their jealousy was provoked by Israel accepting Jesus of Nazareth as God's Son and Saviour. This jealousy was and is surely a reflection of a bad conscience, just as subconsciously Joseph's brothers knew that Joseph was not dead but alive, and standing before them. It was Israel's 'knowledge' of the Gospel they had heard which is related by Paul to their anger and jealousy. And we see the same today in many who exhibit anger and jealousy over the faith of others. This is a function of their 'knowledge' which they are in denial of.</p>
