18. But I say, Have they not heard?--"Did they not hear?" Can Israel, through any region of his dispersion, plead ignorance of these glad tidings?
      Yes, verily, their sound went--"their voice went out"
      into all the earth, and their words unto the end of the world--These beautiful words are from Ps 19:4. Whether the apostle quoted them as in their primary intention applicable to his subject (as OLSHAUSEN, ALFORD, &c.), or only "used scriptural language to express his own ideas, as is done involuntarily almost by every preacher in every sermon" [HODGE], expositors are not agreed. But though the latter may seem the more natural since "the rising of the Sun of righteousness upon the world" (Mal 4:2), "the Dayspring from on high visiting us, giving light to them that sat in darkness, and guiding our feet into the way of peace" (Lu 1:78, 79), must have been familiar and delightful to the apostle's ear, we cannot doubt that the irradiation of the world with the beams of a better Sun by the universal diffusion of the Gospel of Christ, must have a mode of speaking quite natural, and to him scarcely figurative.
