Fascinating that the article does no investigation of Abram, but goes on and on about Abraham.
Ram is thunder in Hebrew.
Hebrew is funny, a tea kettle is called a cum-cum, which is up-up, because the water rises in boiling. It's a rather primitive language, relatively easy to learn. It's given more sophistication in translation by choosing words like "exhalted" rather than the simpler direct translation which is "thunder." Thunder can mean exhalted because it's associated with the exhalted ancient storm gods.
