What Does Genesis 18:8 Mean?

He then brought some curds and milk and the calf that had been prepared, and set these before them. While they ate, he stood near them under a tree. The meal set before the three visitors includes the prepared calf plus curds and milk, the full provision of a patriarchal feast. Abraham serves and then stands nearby while they eat, the stance of the attentive host who remains available but does not intrude on the guests' eating. The standing while they sit and eat is the visual embodiment of the service orientation he has maintained throughout the preparation and welcome.

The detail "while they ate" establishes that the three visitors ate the food prepared for them. They are specifically symbolic presences; they participate in the ordinary human activity of eating the ordinary human food that Abraham has prepared. The eating of the divine visitors is one of the theological puzzles of the chapter: do spiritual beings eat? Later in the narrative, the two Angels who go to Sodom (chapter 19) also eat the food Lot prepares. The pre-incarnate divine presence taking on the activities of embodied human existence is the furthest the Old Testament reaches in the direction of the Incarnation, where the Word became flesh and ate and drank with His disciples.

The standing while they ate is Abraham's continued self-positioning as servant of the guests. He has run, hurried, prepared, served; now he stands at attention for any further need they might have. The servant-stance of the covenant patriarch before the one who appears as travelers is the character that Philippians 2 describes as the mind of Jesus: "who, being in very nature God, did not consider equality with God something to be used to his own advantage; rather, he made himself nothing by taking the very nature of a servant." The God who appears as a traveler needing food and water is practicing in the patriarchal narrative what He will enact permanently in the Incarnation.
