Genesis 18:3
3. My Lord, if now I have found favor—The hospitalities offered are just of the kind that are necessary and most grateful, the refreshment of water, for feet exposed to dust and heat by the sandals, being still the first observed among the pastoral people of Hebron.
Genesis 18:5
5. for therefore are ye come—No questions were asked. But Abraham knew their object by the course they took—approaching directly in front of the chief sheik's tent, which is always distinguishable from the rest and thus showing their wish to be his guests.
Genesis 42:7
7, 8. Joseph saw his brethren, and he knew them, . . . but they knew not him—This is not strange. They were full-grown men—he was but a lad at parting. They were in their usual garb—he was in his official robes. They never dreamt of him as governor of Egypt, while he had been expecting them. They had but one face; he had ten persons to judge by.
made himself strange unto them, and spake roughly—It would be an injustice to Joseph's character to suppose that this stern manner was prompted by any vindictive feelings—he never indulged any resentment against others who had injured him. But he spoke in the authoritative tone of the governor in order to elicit some much-longed-for information respecting the state of his father's family, as well as to bring his brethren, by their own humiliation and distress, to a sense of the evils they had done to him.
