Hazezon Tamar is a beloved general, but where did he get that weird name?
Magic: The Encyclopedia is here to answer your question! Sit back and enjoy some Old Testament (Hebrew and English quoted from Mechon-Mamre.org) while I explain the depths of M:TG flavor.
Genesis, 14:7 -
וַיָּשֻׁבוּ וַיָּבֹאוּ אֶל-עֵין מִשְׁפָּט, הִוא קָדֵשׁ, וַיַּכּוּ, אֶת-כָּל-שְׂדֵה הָעֲמָלֵקִי—וְגַם, אֶת-הָאֱמֹרִי, הַיֹּשֵׁב, בְּחַצְצֹן תָּמָר
And they turned back, and came to En-mishpat—the same is Kadesh—and smote all the country of the Amalekites, and also the Amorites, that dwelt in Hazazon-tamar.
Chronicles 2, 20:2 -
וַיָּבֹאוּ, וַיַּגִּידוּ לִיהוֹשָׁפָט לֵאמֹר, בָּא עָלֶיךָ הָמוֹן רָב מֵעֵבֶר לַיָּם, מֵאֲרָם; וְהִנָּם בְּחַצְצוֹן תָּמָר, הִיא עֵין גֶּדִי
Then there came some that told Jehoshaphat, saying: ‘There cometh a great multitude against thee from beyond the sea from Aram; and, behold, they are in Hazazon-tamar‘—the same is En-gedi.
In the above verses we see that Hazezon Tamar is not in fact a historical person, but a historical place. Interestingly, in both Genesis and Chronicles it is mentioned in association with a battle. In Genesis it is mentioned as the dwelling place of the Amalekites and Amorites that was sacked by Chedarlaomer, the King of Elam. In Chronicles it is the site of a most miraculous victory by the Israelites over a massive army sent against them from Aram (the Preists sang and the Lord caused the invading army to be slain by an ambush and internal strife; note that in Genesis Abraham ends up conquering Chedarlaomer with an ambush in the nighttime… parallels abound).
Most interesting in my opinion are the locations that the Bible identifies as Hazezon Tamar. In Genesis, the location is identified as En-Mishpat/Kadesh, a desert area. Chronicles that tells us Hazezon Tamar is in fact En-Gedi. Ein Gedi is an Oasis in Israel- that means it is a small area of water and greenery in the middle of a desert. What better place to gather together an army of Sand Warriors?
