Commentary
Matthew Henry on Psalms 108:1-5
We may here learn how to praise God from the example of one who was master of the art. 1. We must praise God with fixedness of heart. Our heart must be employed in the duty (else we make nothing of it) and engaged to the duty (Psa 108:1): O God! my heart is fixed, and then I will sing and give praise. Wandering straggling thoughts must be gathered in, and kept close to the business; for they must be told that here is work enough for them all. 2. We must praise God with freeness of expression: I will praise him with my glory, that is, with my tongue. Our tongue is our glory, and never more so than when it is employed in praising God. When the heart is inditing this good matter our tongue must…
For thy mercy is great above the heavens,..... It is in Psalm 57:10, "thy mercy is great unto the heavens". See Gill on Psalm 57:10.

Psalm 108:1-13
A Song or Psalm of David.
1. My heart is prepared, O God! my heart is prepared; I will sing and give praise, even with my glory. 2. Awake, psaltery and harp: I will arise at break of day. 3. I will praise thee, O Jehovah! among the people; and sing unto thee among the nations: 4. Because thy goodness is great above the heavens, and thy truth unto the clouds. 5. Be thou, O God! exalted above the heavens; and thy glory above all the earth: 6. That thy chosen may be set free, save me by thy right hand, and hear me. 7. God has spoken in his holiness; I will rejoice, I will divide Shechem, and measure the valley of Succoth. 8. Gilead is mine; Manasseh is mine; Ephraim is the stre…
This first half is taken from Ps. 57:8-12. The repetition of confident is my heart in Psa 57:1-11 is here omitted; and in place of it the "my glory" of the exclamation, awake my glory, is taken up to "I will sing and will harp" as a more minute definition of the subject (vid., on Psa 3:5): He will do it, yea,his soul with all its godlike powers shall do it. Jahve in Psa 108:4 is transformed out of the Adonaj; and Waw copul. is inserted both before Psa 108:4 and Psa 108:6, contrary to Psa 57:1-11. מעל, Psa 108:5 (as in Est 3:1), would be a pleasing change for עד if Psa 108:5 followed Psa 108:5 and the definition of magnitude did not retrograde instead of heightening. Moreover Psa 36:6; Jer 51…
The Church Fathers
Of the Greeks, some have said that God is the soul of the world; others that his power does not extend to earth but only to heaven. Some, laboring under a similar delusion, misinterpret the text "and your faithfulness to the skies" and have dared to limit the providence of God to the skies and heaven and to alienate from God the things on earth, forgetting the psalm that says, "If I go up to the heavens, you are there; if I sink to the underworld, you are present there." For if there is nothing higher than heaven and the underworld is deeper than the earth, he who rules the lower regions reaches the earth also.
"For your mercy is great above the heavens." There is no creature that does not stand in need of God's mercy. All of us stand in need of God's mercy. Gabriel, Michael, the Seraphim, the Cherubim, the Powers, the Dominions, are indeed holy, but they stand in need of the mercy of their creator. I do not disparage the angels, but I proclaim the creator; since the angels themselves gladly have their creator proclaimed. And we can say it another way: "For your mercy raises up from the earth to the heavens. And your truth reaches even to the clouds." Where are the Jews, where are those like the Jews, who understand only according to the letter? How is the truth of God "even to the clouds"? The Son of God says, "I am the way and the life and the truth": and he descended to the earth, and dwelt among men. And how is your truth "even to the clouds"? The sense is plain, that he speaks of the apostles and of the saints, that they should not rain their rain upon the Jews, but upon the Gentiles, as it is written: "I will command my clouds not to rain rain upon Israel." In these clouds, then, is the truth of God. But if the truth of God is in these clouds, how does Montanus say, and how do the Cataphrygians say, that what was not revealed to the apostles has been revealed to us?

Spurgeon's Treasury of David on Psalms 108:4
For thy mercy is great above the heavens: and thy truth reacheth unto the clouds.
For thy mercy is great above the heavens, and therefore there must be no limit of time, or place, or people, when that mercy is to be extolled. As the heavens over arch the whole earth, and from above mercy pours down upon men, so shalt thou be praised everywhere beneath the sky. Mercy is greater than the mountains, though they pierce the clouds; earth cannot hold it all, it is so vast, so boundless, so exceeding high that the heavens themselves are over topped thereby. And thy truth teacheth unto the clouds. As far as we can see we behold thy truth and faithfulness, and there is much beyond which lies shroude…
