What does Genesis 18:5 mean?
Abraham continues to plead with the three men who appeared near his tent not to leave too quickly. One of the men is the Lord in human form. The other two are angels also disguised as humans.After asking them to receive rest and water and the washing of their feet in the previous verse, Abraham now includes the offer of a morsel of bread before they pass on. As the following verses will reveal, Abraham is vastly understating the meal he plans to provide.
Abraham, a wealthy and powerful man with many servants, refers to himself as the servant of these men. Indeed, he acts as if he were a servant eager to please his master. This might have been Abraham's way of expressing his culture's typical approach to hospitality. Or, his extravagant response might have been because he knew, immediately, with whom he was speaking.
Finally, the strangers agree to wait while Abraham provides for their refreshment.
