Romans 15:12

‘And again, Isaiah says, “There will be the root of Jesse, and he who arises to rule over the Gentiles, on him will the Gentiles hope.” '

Once more, in a citation from Isaiah 11:10 LXX, emphasis is laid on the Messiah, the root of Jesse, and the fact that the Gentiles will look to Him. So Paul opens and closes his citations with a reference to the Messiah. In this verse, however, there is no mention of the glorifying of God which has been the feature of the previous three quotations. Rather the emphasis is on the fact that the Messiah of the Jews will rule over the Gentiles also, and will be the One in Whom the Gentiles ‘hope', that is, the One to whom they will look for blessing and eternal life. Out of the root will grow the engrafted branches (Romans 11:16).
