Mount Hor, in the Jewish writers, is Amanah; mention of which occurs, Canticles 4:8, where R. Solomon thus: "Amanah is a mount in the northern coast of the land of Israel, which in the Talmudical language is called, The mountainous plain of Amanon; the same with mount Hor."
In the Jerusalem Targum, for mount 'Hor' is the mount Manus: but the Targum of Jonathan renders it The mountain Umanis.
"What (say the Jerusalem writers) is of the land of Israel, and what without the land? Whatsoever comes down from mount Amanah inwards is of the land of Israel; whatsoever is without the mountainous place of Amanah is without the land."
And a little after; "R. Justa Bar Shunem said, When the Israelites that return" (from their dispersion), "shall have arrived at the mountainous places of Amanah, they shall sing a song; which is proved from that which is said (Canticles 4:8), He renders it, Thou shalt sing from the head of Amanah."
There was also a river of the same name with the mountain, of which the Targum in that place; "They that live by the river Amanah, and they that live on the top of the mountain of snow, shall offer thee a present." And the Aruch, which we have noted before, writes thus; "Kirmion is a river in the way to Damascus, and is the same with Amanah."
"The mountain of snow," among the paraphrasts and Talmudists, is the same with Hermon. The Samaritan interpreter upon Deuteronomy 4:48, "To the mountain of snow which is Hermon." And the Jerusalem writers say, "They built for the daughters of the Midianites little booths of hurdles from Beth-Jeshimon unto the mountain of snow, and placed there women selling cakes."
The Jerusalem Targum upon Numbers 35 writes thus; "The mountain of snow at Caesarea" (Philippi). See also Jonathan there.
