What does Romans 15:10 mean?
Paul is providing several quotations from Old Testament Scriptures to support the idea that Christ came to serve the Jews both to fulfill God's promises to them and to cause the Gentiles to glorify Him.This is a quote from a text similar to Deuteronomy 32:43, though it reads differently from that specific passage. Paul uses the quote to show that the Gentiles will rejoice along with God's chosen people, the Jews. Within the context of this passage, Paul is showing that God's plan was always to show mercy to both the Gentiles and the Jews as they came to Him through faith in Christ. Then they would rejoice and praise God together.
