William Henry York's "Health and Wellness in Antiquity Through the Middle Ages" mentions an Ashipu ritual whereby a Lilu and Lilitu demon would be "united in marriage" and sent off "to a properly provisioned home in the netherworld, thus placating them".
I've never heard of this before and I'd be very interested to learn more about this if possible, as York doesn't seem to provide an immediate source for that statement.
