Augustine of Hippo
As the morning light rises, the psalter is lifted up in praise, expressing gratitude to the Lord. What does it declare? "I will praise You among the nations, O Lord, and I will sing Your praises among the people; for Your mercy reaches to the heavens, and Your truth to the clouds" (Psalm 56:10). Heaven is situated above the clouds, which themselves are found beneath the sky; yet even the clouds are part of this nearest heaven. At times, the clouds are seen resting upon the mountains while still being part of the surrounding air. Nevertheless, there exists a higher Heaven, the abode of Angels, Thrones, Sovereignties, Dominions, Powers, and Authorities.

Thus, it could be rightly stated, "Your truth is exalted to the heavens, and Your mercy to the clouds." In Heaven, the Angels exalt the Lord, perceiving the essence of truth without any shadow of imperfection or mingling with falsehood: they behold, they love, they worship, and they do not tire. Here on earth, while truth exists, in our state of suffering, mercy is essential. Those in distress require mercy, for where there is no anguish, mercy is unnecessary. It is for this reason that it is fitting to proclaim, "Your truth reaches to the heavens, and Your mercy to the clouds." We regard the clouds as messengers of truth, vessels of flesh who communicate the divine amid darkness, through which God manifests in miracles and delivers His commandments.
Let us glorify our Lord, His Mercy, and the very Truth, for He has not withheld mercy, bringing us blessing through His Grace, nor has He deprived us of the truth: for initially, the Truth that was veiled in flesh came among us, healing the inner eye of our hearts so that, in the fullness of time, we might one day behold it face to face (1 Cor. 13:12).
