Tonight is the Night Vigil for Wesir, the dead god, during His Mysteries.
From T. Siuda’s translation of the Lamentations of Aset (Isis) and Nebt-het (Nephthys):
Your two sisters join together Your limbs,
and no pain shall touch You.
We will make Your injury as if it never happened.
Great Mighty One among the gods,
the road You travel cannot be described.
