“For thy mercy is magnified even to the heavens: and thy truth unto the clouds.”
“Giving therefore to Him thanks, let us say with the same Psalm the last verses, which sometime since too I have said, "Be Thou exalted above the Heavens, O God, and above all the earth Your glory." For this to Him the Prophet said so many years before; this now we see; this therefore let us also say.”
“Clouds. They are exceedingly great. (Haydock) — Christ has mounted to the highest heavens, and his apostles have preached (Calmet) his saving truths, which, like clouds, render the earth fruitful in good works. (Haydock)”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
