Psalm 19 is a magnificent example of Hebrew poetry; which speaks of the wonders of the Almighty's creative hand evident in the stars; and our sun in particular. Hayden's Creation Hymn draws thoughts from this Psalm - "the unwearied sun from day-to-day doth His Creator's power display ...". Surely when we gaze upon the night sky, as Abram was asked to do in Genesis 15, we are caused to wonder at the awesome power on display (Genesis 1 says he just scattered the stars from His hand). On day 4 the sun was appointed to rule the day - emblematic of the sun of righteousness (Malachi 4; Matthew 13verses43).
Verse 3 tells us that the universal message is that there must be an Omnipotent Creator (Romans 1verses20); and they = Sun, moon and star - symbolically proclaim the gospel message (Romans10verses18). In the Psalm David says that the sun is like a strong man running a race; it is also like a bridegroom - the Lord Jesus Christ (John 3). The Psalm finishes by exhorting the reader to contemplate the sweetness and preciousness of God's Word; and its saving power.
Psalm 20 continues the theme of trusting in Yahweh's saving strength. This might is in no horse; no battle weapon; no man. But it has been consistently and dependably exercised by God in the cause of delivering the faithful.
