the Hebrew word for moon, "lebanah," is a feminine noun while the Hebrew for full, "maw-la," is male yet can mean “pregnant woman;” the Hebrew given over the Egyptian is keseh, which is masculine; see Psalm 81:3; this is likely pointing to the restoration of the Sabbath of the Full Moon; while the New Moon Sabbath was overseen by the male Levite Priests, it is believed that the Full Moon Sabbath may have been overseen by the Levite Priestess until these daughters of Miriam were shut away.
See Doctrines of the Saints 123, see also Lebanah.
