הלא הוא כמס עמדי IS NOT THIS LAID UP IN STORE WITH ME — Understand this as the Targum has it: (“Are not all their doings open before me?”) — i.e., they believe that I have forgotten their doings, but really they are all stored up and kept with Me. הלא הוא IS NOT THIS — the fruit of their vine and the produce of their fields (i.e. their doings) כמס עמדי STORED UP WITH ME?”

“Treasures. Whether we refer to the preceding remarks to the faithless Israelites, whose corruption was less pardonable, as they had received so many favours from above, or to their proud and cruel enemies, who exceeded the bounds of moderation in their wars, God keeps an exact account of all, and will shortly punish both, according to their deserts. (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.
