John Wesley on Psalms 19:4

Line - Their lines, the singular number being put for the plural. And this expression is very proper, because the heavens do not teach men audibly, or by speaking to their ears, but visibly by propounding things to their eyes, which is done in lines or writings. Gone - Is spread abroad. Earth - So as to be seen and read, by all the inhabitants of the earth. Words - Their magnificent structure, their exquisite order, and most regular course, by which they declare their author, no less than men discover their minds by their words. Sun - Which being the most illustrious and useful of all the heavenly bodies, is here particularly mentioned.
