Or HaChaim on Leviticus 26:41/אור החיים על ויקרא כ״ו:מ״א

1 אף אני אלך עמם בקרי, "Also I will walk with them as if accidental." Part of what the people have to acknowledge as part of their confession is that all G'd's retributions were justified. Even G'd's having withdrawn His personal supervision over the fate of the Jews must be acknowledged.

2והבאתי אותם, "and I will bring them, etc." This is also part of what the people will say as part of their confession. The fact that the Torah demands that the people acknowledge that their exile was part of G'd's punishment in line with His warnings indicates that they had previously denied that their exile was connected to their wrongdoing. The people had argued that if G'd really wanted to use His retribution to result in the people's repentance, exile was a peculiar means to achieve this. They reasoned that exile was bound to result in assimilation, the very reverse of what G'd wanted to achieve by disciplining His people. Such considerations reinforced the people's thinking that what had befallen them was accidental and not part of G'd's design. This is why G'd wrote that they have to confess also their erroneous assessment of why they had experienced all the curses predicted in the Torah.

3The words או אז mean that the exiled Israelites attribute their presence in other countries to be a result of natural migration or as an attempt by G'd to induce humility in them. G'd had known from experience that a sinner may humble himself such as Achav the king of Israel (Kings I 21, 27-29). Our sages in Berachot 7 have said that "better one severe chastisement which results in the sinner feeling humbled than 100 lashes of the whip (as these are effective only externally). Following such a humbling of oneself their guilt may become something they can acknowledge and come to terms with."
