ירמיהו, פרק כ״ג, פסוק ח׳

The future salvation and redemption of the Israelites will be so profound that it will completely overshadow the Exodus from Egypt. Because of its immense significance, this future gathering will be remembered more than any other event in history. This shift in national memory will be so complete that people will actually change the standard words they use when making a sworn oath [מצודת דוד, ביאור שטיינזלץ].

Instead of swearing by the God who brought them out of Egypt, the Israelites will adopt a new declaration, swearing by God who brought them up from the lands of their exile. Although God speaks directly in the first person about how He distanced and exiled the people, the Israelites will naturally adapt this language when taking their oaths. They will speak in the third person, swearing by God who had previously scattered them [מצודת דוד]. This newly formed oath concludes by focusing on the ultimate, long-awaited result of the ingathering of the exiles: the people will finally return to their homeland and live securely on their own land [מצודת דוד, ביאור שטיינזלץ].
