What does Genesis 18:6 mean?
When God assumes a temporary human form, it is referred to as a theophany. This incident is an example: God, appearing as a man, has arrived with two angels—who also appear to be human—near Abraham's tent. Abraham has responded by bowing before them and urging them to stay while he provides some water and a "morsel of bread" for their refreshment. Abraham's behavior might be the usual ancient eastern approach to hospitality. Or, possibly, he quickly realized that the men he was speaking to were not ordinary men.Now he runs back to the tent and tells Sarah to quickly make cakes, meaning loaves of bread, for the three visitors. However, he tells her to use with three seahs of fine flour. In modern measurements, this would be approximately 21 quarts or liters! That would make an extravagant amount of bread for just three men. But the cakes / loaves are just the beginning. Abraham is engineering a royal feast.
