Romans 10:19-20

19So I ask this too: ‘When Israel's people heard God's message, did they understand it?’ First, think about what Moses wrote. God said to Israel's people: ‘I will make you jealous because of people who are not my people. I will make you angry because of people who know nothing about me.’

20Also, this is what Isaiah said very bravely: ‘God says: Those people who were not looking for me have found me. I showed myself to people who were not even asking about me.’
