Romans 15:10

And again he said, Rejoice, ye Gentiles, with his people. And again, Praise the Lord, all ye Gentiles; And let all the peoples praise, him. And again, Isaiah saith, There shall be the root of Jesse, And he that riseth to rule over the Gentiles; On him shall the Gentiles hope.

These three quotations from Deuteronomy 32:43; Psalms 117:1, and Isaiah 11:10, all make mention of the Gentiles, further strengthening Paul's biblical evidence presented for the purpose of showing that God's purpose always had envisioned the redemption of Gentiles as well as Jews. Behold here the manner of Christianity's greatest preacher in the use of scripture. Paul did not hesitate to pile verse on top of verse and to marshal scripture after scripture in support of his thesis. His greatest writings were liberally salted with verses from the word of God; and the deduction would appear to be justified that God's preachers today should base their sermons upon the sacred word and reinforce their every thought by repeated appeals to a "thus saith the Lord." Failing to do this does not elevate men above the supreme preacher Paul, but, on the other hand, exhibits their weakness and ineffectiveness.

Hope ... at the end of the quotations in this verse seems to have reminded Paul of what he had just written in Romans 15:4; and this possibly accounts for the fact that the closing doxology of this section on the strong and weak brethren (next verse) begins with the expression, "Now the God of hope."
