Psalms 19:4

Their line is gone out through all the earth
Not the line or writings in the book of the creatures, the heavens, and the earth, which lie open, and are legible, and to be seen and read of all men; nor the line and writings in the book of the Scriptures, called line upon line, and precept upon precept, ( Isaiah 28:13 ) , which, though first given to the Jews, were written for the instruction of others, and have been communicated to them; but the line of the apostles: everyone had his line or measure; or the course he was to steer was measured out and directed to him; the line of one, where he was to go and preach the Gospel, reached so far one way, and the line of another reached so far another way; and what with one and another, their line reached throughout all the earth; see ( 2 Corinthians 10:13-16 ) ; the apostle citing these words in ( Romans 10:18 ) ; renders them, "their sound went" the sound of the Gospel, as published by them; which agrees with the next clause;

and their words to the end of the world;
to the isles afar off, even to these northern and distant ones of England, Scotland, and Ireland, which were reached and visited with the Gospel, either by the apostles, or at least by some of the first ministers of the word;

in them hath he set a tabernacle for the sun;
that is, in the heavens and firmament, where the natural sun is placed; and its habitation is fitly called a tabernacle, because it is always in motion and never stops: or this may have some respect to its setting, when, according to the common appearance, and to common understandings, it seems to be hid as in a tent or tabernacle; to be as it were gone to bed, and at rest; when in the morning it rises gay and cheerful, and comes forth like a bridegroom out of his chamber, as is said in ( Psalms 19:5 ) : but this is all to be understood, spiritually and mystically, of Christ the sun of righteousness, who has his tabernacle among his people, his churches; and particularly has a place, and the chief place, in the ministry of the Gospel, being the sum and substance of it; and this is of God's putting there, who committed to his apostles the word of reconciliation, the sum of which is Christ; and this is what makes the Gospel so glorious a light, so clear a revelation as it is: the nature, continuance, and extent of this revelation, are described in the foregoing verses; the perspicuity and clearness of it is set forth in this clause, and in what follows.
