 and waited upon them as the host, they asked for Sarah, for whom the visit was chiefly intended. On being told that she was in the tent, where she could hear, therefore, all that passed under the tree in front of the tent, the one whom Abraham addressed as Adonai (my Lord), and who is called Jehovah in Gen 18:13, said, “ I will return to thee (חיּה כּעת) at this time, when it lives again” (חיּה, reviviscens, without the article, Ges. §111, 2 b), i.e., at this time next year; “ and, behold, Sarah, thy wife, will (then) have a son.” Sarah heard this at the door of the tent; “ and it was behind Him” ( Jehovah), so that she could not be seen by Him as she stood at the door.

Abraham accompanied them some distance on the road; according to tradition, he went as far as the site of the later Caphar barucha, from which you can see the Dead Sea through a ravine, - solitudinem ac terras Sodomae. And Jehovah said, “Shall I hide from Abraham what I propose to do? Abraham is destined to be a great nation and a blessing to all nations (Gen 12:2-3); for I have known, i.e., acknowledged him (chosen him in anticipative love, ידע as in Amo 3:2; Hos 13:4), that he may command his whole posterity to keep the way of Jehovah, to practise justice and righteousness, that all the promises may be fulfilled in them.” God then disclosed to Abraham what he was about
