She was a witness for God to the Gentile world, that he had not utterly forsaken them, but that in due time they should become one with his chosen people, and partake of his salvation.

What a pity it is that pious language should not be more used among Christians, or that it should be let fall into formality! Here is the descent of David from Ruth. And the period came when Bethlehem-Judah displayed greater wonders than those in the history of Ruth, when the outcast babe of another forlorn female of the same race appeared, controlling the counsels of the Roman master of the world, and drawing princes and wise men from the east, with treasures of gold, and frankincense, and myrrh to his feet. His name shall endure for ever, and all nations shall call Him blessed. In that Seed shall all the nations of the earth be blessed.
