The Liturgy of Funeral Offerings: Chapter III: Description of the Offerings: The Eleventh Ceremony
The text of Peta-Amen-apt is somewhat fuller, and reads:--
"[That which floweth] from the breast of Horus, and is of his body, hath been presented unto thee for thy mouth. That which cometh from the breast of thy sister Isis, the emission of thy mother, hath been seized by thee for thy mouth, and thou openest thy mouth by means of it."
