What does Genesis 18:7 mean?
The text here makes clear that Abraham is hurrying. Having convinced three unexpected visitors, including God in human form, to stay and allow Abraham to provide them water and a bit of bread, Abraham now rushes to provide them with a feast.In the previous verse, Abraham told Sarah to quickly make cakes of bread for them. He specified that she should use more than five gallons, some 21 liters, of fine flour; this would have made a very large banquet of bread. Now, the wealthy and powerful Abraham hurries to his herd of cattle and grabs a tender calf to give to a young male servant to quickly prepare for the meal.
Abraham is both eager to serve the Lord and eager for them not to leave. Abraham behaves as the Lord's servant, exhibiting both the warm hospitality of a good host and an attitude of submission. His passion is revealed in the terms used in this passage: Abraham "went quickly" (Genesis 18:6), he "ran," and the young man prepared the meat "quickly."
