How Do the Gentiles Glorify God for His Mercy?

The answer is given in the four quotations from the old testament, in verses nine through 12. And you notice that gentiles are mentioned in every quotation. But keep your eyes pealed for a clue as to who they are. As it is writt therefore i will praise you among the gentiles and sing to your name. In him will the gentiles hope. That's not just abraham, isaac and jacob, the fathers. That's david, that's moses. The promises made to the patriarchs are so about the the nations the gentiles.
