Charles Ellicott Commentary Numbers 34:8

"from mount Hor ye shall mark out unto the entrance of Hamath; and the goings out of the border shall be at Zedad;" — Numbers 34:8 (ASV)

From Mount Hor ... — From Mount Hor the boundary line was to pass the unknown Ziphron to the village of Enan, or Hazar-enan, which is likewise unknown. (Compare to Ezekiel 47:16-18.) This line probably crossed the northern portion of the Lebanon.
