Musar zu Daniel 9:9

And the order of the confession is - “We have sinned, we have been iniquitous, we have transgressed (chatanu, avinu, pashanu).” And sin includes inadvertent sin and peshiyah. And the meaning of peshiyah, according to the Sages of Israel, is when one is not careful about a matter about which it is the way of most people to be careful, as we have already mentioned. And iniquities (avonot) are volitional sins. And transgressions (peshayim) are acts of rebellion, from the usage (in II Kings 3:7), “The king of Moab has rebelled (pasha) against me. And - according to His great Kindness, God, may He be blessed, forgives even those who rebel against Him, when they repent to Him with all of their hearts. And it is stated (Daniel 9:9), “To the Lord, our God, belong mercy and forgiveness; for we rebelled (pashanu) against Him.” And it is stated (Psalms 25:11), “For the sake of Your name, O Lord, pardon my iniquity (avoni) though it be great.” And it is stated (Psalms 65:4), “All manner of iniquities overwhelm me, it is You who forgives our transgressions (peshaeinu).”
