Just keep the rations coming, please.

The ancient Egyptians believed early on that to obtain eternal life, the individual must join the gods after death. Since to ancient Egyptians, death was thus merely a continuation on a different plane of existence of the life they had known, shelter and material goods were considered necessary for the deceased’s well-being. A tomb equipped with clothing and everyday utensils as well as food and drink would supply those needs.
The hetep-di-nisu, or “a gift which the king gives”, is the offering formula or prayer asking for offerings to be given to the deceased.

But, surely they really didn’t expect offerings to be continued forever, which is why inscriptions of offerings and the King making them are found in their tombs, a substitute for the actual on walls and in papyrus or coffins..

Why the King, and not one of the family of the deceased? It had to do with their religious beliefs and practices. The king was the main priest, the only actual priest in Egypt, it was only the king who was ever shown making offerings to the gods in the temples. This practice carried over to the tombs, for the King was the only one who could make the bargain with the gods to ensure a happy afterlife.

On the ‘Bounty of the Gods’, the distribution of offerings:

…offerings went from the temple to the necropolis. Since the Old Kingdom, the practice was that offerings presented to the main god of the temple were carried out of the sanctuary, presented to gods having subsidiary cults in the temple, then to statues of kings and private persons placed in the temple courts, and finally to the necropolis. The offerings were then distributed to the priests and all the staff involved in the rituals as a reward, or salary, for their work.
