Psalm 19 The Glory of God in Creation and the Law
1 The heavens are telling the glory of God;
and the firmament proclaims His handiwork.
2 Day to day pours forth speech,
and night to night declares knowledge.
3 There is no speech, nor are there words;
their voice is not heard;
4 yet their voice goes out through all the earth,
and their words to the end of the world.
In them He has set a tent for the sun,
5 which comes forth like a bridegroom leaving his chamber,
and like a strong man runs its course with joy.
6 Its rising is from the end of the heavens,
and its circuit to the end of them;
and there is nothing hid from its heat.
7 The law of the Lord is perfect,
reviving the soul;
the testimony of the Lord is sure,
making wise the simple;
8 the precepts of the Lord are right,
rejoicing the heart;
the commandment of the Lord is pure,
enlightening the eyes;
9 the fear of the Lord is clean,
enduring for ever;
the ordinances of the Lord are true,
and righteous altogether.
10 More to be desired are they than gold,
even much fine gold;
sweeter also than honey
and drippings of the honeycomb.
11 Moreover by them is Thy servant warned;
in keeping them there is great reward.
12 But who can discern His errors?
Clear Thou me from hidden faults.
13 Keep back Thy servant also from presumptuous sins;
let them not have dominion over me!
Then I shall be blameless,
and innocent of great transgression.
14 Let the words of my mouth and the meditation of my heart
be acceptable in Thy sight,
O Lord, my rock and my redeemer.
– Psalm 19
Commentary based on St. Thomas Aquinas
Psalm 19, according to the letter, refers to David. But according to the mystery, it refers to Christ.
The psalmist mentions the heavens, and here, in order to show the praise of the creator, he mentions the sun.
As by the heavens, we understand the Apostles, so also by the sun we understand Christ.
Some prophecies say this of Christ under the figure of the sun.
Thus, he presents the figure by which he begins to explain the truth about Christ.
