“On the south side,
It shall run
From Tamar
As far as
The waters
Of Meribath-kadesh.
From there
It shall run
Along the Brook of Egypt
To the Great Sea.
This shall be the south side.”
The southern border in Numbers, chapter 34 was also vague. However, there was a mention of the Dead Sea and the Wilderness of Zin. Here the border goes almost to Egypt, to the great sea, or the Mediterranean Sea. Tamar, just mentioned on the eastern border, is the start of this southeast border. Meribath-kadesh was in the wilderness of Zin, south of the Dead Sea.
