His going forth is from the end of the heaven, and his circuit unto the ends of it: and there is nothing hid from the heat thereof.
And there is nothing hid from the heat thereof. "Heat" here includes light, which is its accompaniment; because the word "hid" must primarily refer to light. There is nothing hid from its all-warming light, which is the handmaid to life (cf. John 1:4; John 1:8-9), as to the antitypical light.
The all-penetrating power of the sun (Psalms 19:6) forms the natural transition to the spiritual Sun. The section Psalms 19:7-10 sets forth the glories of the law, which emanates from the same God whose praises the heavens declare (Psalms 19:1-6). In the Psalms 19:7-9 twelve marks of praise are ascribed to the law, forming six pairs, in which the second mark of praise in each pair is related to the first as effect to cause; accordingly, no copula precedes the second, and the name of Yahweh occurs in the first member alone. Thus, in Psalms 19:7, "The law of the Lord is perfect, (and hence) it converts the soul: the testimony of the Lord is sure, (and hence) it makes wise the simple." In Psalms 19:7-8 the effects are those which the law produces on the soul and heart of man. In Psalms 19:10 the preciousness and sweetness of the words of God are indicated generally.
