Where would Joseph Smith have learned about Libnah?

In Abraham 1:13 we read of the god Libnah:

It was made after the form of a bedstead, such as was had among the Chaldeans, and it stood before the gods of Elkenah, Libnah, Mahmackrah, Korash, and also a god like unto that of Pharaoh, king of Egypt.

Jeff Lindsay explains:

One Hebrew text, The Story of Abraham, uses essentially the same word (identical if written without vowels, as was done in early Hebrew texts), meaning “white one,” to refer to Abraham’s brief, misguided worship of the moon on one evening as a three-year-old child seeking to know what to worship. The Hebrew text makes repeated mention of the moon, but in all other instances uses a different Hebrew word. It’s interesting that in a case where someone is praying to the moon as if it were a god, a text about Abraham would use the same name of a false god listed in the Book of Abraham. (The other Hebrew word for moon used in this text is “yareah,” which may be related to “Olea” in Abraham 3:13, said to signify the moon – based on the fact that in ancient Egyptian, a Semitic language related to Hebrew, the letters l and r were identical (yareah = yaleah = Olea?).)

Where would Joseph Smith have gotten the idea of “Libnah” as a god?
