63 And he possessed also a steward of his house who set signs for himself[Genesis 24. 2, 10, 43]. And if one of you doubts this, the very words which were uttered by Moses concerning it will show him clearly : After these sayings the word of the Lord came unto Abraham in a vision of the night, sayings Fear not, Abraham: I am thy shield. Thy reward shall be exceeding great. And Abraham said. Lord God what wilt thou give me? For I go childless, and the son of Masek the slave woman will be my heir. And straightway the word of the Lord came unto him saying, This man shall not be thine heir: but he that shall come forth from thee shall be thine heir. And he brought him forth and said unto him, Look now toward heaven, and tell the stars, if thou be able to number them : and he said unto him, So shall thy seed be. And Abraham believed in the Lord: and it was counted to him for righteousness.[ Genesis 15. 1-6]
64 Tell me now why he who dealt with him, whether angel or God, brought him forth and showed him the stars? For while still within the house did he not know how great is the multitude of the stars that at night are always visible and shining? But I think it was because he wished to show him the shooting stars, so that as a visible pledge of his words he might offer to Abraham the decision of the heavens that fulfills and sanctions all things. And lest any man should think that such an interpretation is forced, I will convince him by adding what comes next to the above passage. For it is written next: And he said unto him, I am the Lord that brought thee out of the land of the Chaldees, to give thee this land to inherit it. And he said, Lord God, whereby shall I know that I shall inherit it? And he said unto him, Take me an heifer of three years old, and a she-goat of three years old, and a ram of three years old, and a turtle-dove and a pigeon. And he took unto him all these, and divided them in the midst, and laid each piece one against another; but the birds divided he not. And the fowls came down upon the divided carcases, and Abraham sat down among them.
