The Egyptian Book of the dead by P. Le Page Renouf and Edouard Naville

1. _In Chemmis._ The name of the place where Isis gave birth to Horus is

in the Pyramid texts written ⁂⁂⁂⁂ (Pepi I, 428), and ⁂⁂⁂ (Merenra I, 683), _aḫ-ḫebit_ or _ḫebit-aḫ_; but simply _ḫebit_ in the texts of the eighteenth dynasty, as in the annals of Thothmes III (Mariette, _Karnak_c pl. 16, line 47),[54] or in the divine and proper names ⁂⁂⁂⁂⁂, ⁂⁂⁂⁂⁂⁂⁂, ⁂⁂⁂⁂⁂⁂, ⁂⁂⁂⁂⁂⁂, and ⁂⁂, ⁂⁂⁂⁂, ⁂⁂⁂⁂. It is certain therefore that the sign ⁂ is here only an ideogram of ⁂⁂⁂, not of the ancient ⁂⁂⁂. From the eighteenth dynasty at least, and for a time belonging to a period of unknown length between the sixth and the eighteenth dynasties, and for ever afterwards, the name of the place was ⁂⁂⁂⁂⁂ _Ḫebit_, where, as the _Tablet of the Dream_ says, ⁂⁂⁂⁂⁂⁂⁂ (Mariette, _Mon. div._, pl. 7).
