Psalms 19:1

“The heavens declare the glory of God, etc.] By which we are to understand not the heavens literally taken, though these with the firmament are the handiworks of God, and do declare the glory of his perfections, especially his wisdom and power; these show that there is a God, and that he is a glorious one: but either Gospel churches, often signified by the kingdom of heaven, in the New Testament; the members of them being heaven-born souls, and the doctrines and ordinances ministered among them being from heaven; and there being a very great resemblance between them and heaven, in the company and communion enjoyed in them; and who declare the glory of the divine perfections, which is very…”

“After exhibiting the harmonious revelation of God's perfections made by His works and His word, the Psalmist prays for conformity to the Divine teaching. (Psa 19:1-14) the glory of God--is the sum of His perfections (Psa 24:7-10; Rom 1:20). firmament--another word for "heavens" (Gen 1:8). handywork--old English for "work of His hands."”

“The heavens declare the glory of God - They announce, proclaim, make known his glory. The word heavens here refers to the material heavens as they appear to the eye - the region of the sun, moon, and stars. The Hebrew word is used in the Scriptures uniformly in the plural number, though in our common translation the singular number is often used. Genesis 1:1, Genesis 1:8-9, Genesis 1:14, Genesis 1:17, Genesis 1:20; Genesis 6:17; Genesis 7:11, Genesis 7:19, Genesis 7:23; et soepe. The plural, however, is often retained, but without any special reason why it should be retained in one place rather than in another. Genesis 2:1, Genesis 2:4; Deuteronomy 10:14; Ezra 9:6; Psalms 2:4; Psalms 8:1,…”

“The heavens - They are as a legible book, wherein he that runs may read it. The glory - His eternal power and Godhead, his infinite wisdom and goodness. Firmament - Or, the expansion, all the vast space extended from the earth to the highest heavens, with all its goodly furniture. Psalms 19:2”

“Ps 19 God’s wisdom is manifest in heaven (19:1-4), in nature (19:4-6), in his instruction (19:7-11), and in the life of the psalmist (19:12-14). Like Ps 8, this hymn uses creation to motivate reflection—it is a peaceful oasis after the drama of the lament and victory psalms. The psalm begins with creation as a source of wisdom, then moves to God’s word as the perfect source of wisdom, and ends with the human need for redemption. 19:1-4 The created order is an arena of God’s wisdom, and the heavens are the place of God’s dwelling (2:4; see 8:1; 57:5; 89:6; 115:3). From heaven, God observes humanity (11:4; 14:2; 33:13; 53:2; 80:14; 102:19) and comes to the rescue of his servants (18:6-8, 13;…”

“The heavens: Psa 8:3, Psa 33:6, Psa 115:16, Psa 148:3, Psa 148:4; Isa 40:22-26; Jer 10:11, Jer 10:12; Rom 1:19, Rom 1:20 the firmament: Rakeea, from raka, to stretch out, the expanse, not only containing the celestial bodies, but also the air, light, rain, dews, etc., all of which display the infinite power and wisdom of their Almighty Creator. Psa 150:1, Psa 150:2; Gen 1:6-8, Gen 1:14, Gen 1:15; Dan 12:3 Psalms 19:2”

“(Heb.: 19:2-4) The heavens, i.e., the superterrestrial spheres, which, so far as human vision is concerned, are lost in infinite space, declare how glorious is God, and indeed אל, as the Almighty; and what His hands have made, i.e., what He has produced with a superior power to which everything is possible, the firmament, i.e., vault of heaven stretched out far and wide and as a transparency above the earth (Graeco-Veneta τάμα =ἔκταμα, from רקע, root רק, to stretch, τείνειν), distinctly expresses. The sky and firmament are not conceived of as conscious beings which the middle ages, in dependence upon Aristotle (vid., Maimonides, More Nebuchim ii. 5), believed could be proved fro this…”
