Genesis 12:14

And it came to pass, that, when Abram was come into Egypt,
&c.] To the city of Heliopolis; for there it was that Abram had his abode, as Eupolemus ^F18 says, when upon the famine he went into Egypt, and where he conversed with the Egyptian priests, and taught them astrology, and other things belonging to it; and of this descent of Abram into Egypt, and teaching astrology, Artapanus ^F19, another Heathen writer, speaks; Abram, he says, having learned the science of astrology, went first into Phoenicia and taught it the Phoenicians, and afterwards went into Egypt, and taught it there.

[The] Egyptians beheld the woman, that she was very fair;
Abram knew that Sarai was a fair woman; but in the eyes of the Egyptians she was very fair, exceeding fair, they not being used to see very beautiful women.
