Deuteronomy 2:5

5 Do not engage in war against them, for I will not give you of their land even enough to set your foot upon, for I have given mount Seir to the children of Esau as an inheritance.

Deuteronomy 2:5 Meaning and Commentary

Ver. 5 Meddle not with them
Contend not with them in battle, nor provoke them to it:

for I will not give you of their land, no not so much as a foot breadth;
or as the sole of a man's foot can tread on, signifying that they should not have the least part of it, not any at all. Jarchi makes mention of an exposition of theirs, that he would give them nothing of it until should come the day of the treading of the sole of the foot in the mount of Olives, ( Zechariah 14:4 ) , meaning not till the days of the Messiah, when Edom should be a possession of Israel; see ( Numbers 24:18 ) , ( Obadiah 1:19 )

because I have given Mount Seir unto Esau for a possession;
and therefore not to be taken away from them; they have a right of inheritance of it; see ( Genesis 36:8 ) ( Joshua 24:4 ) .

Deuteronomy 2:5 In-Context

3 Ye have compassed this mount long enough; turn therefore toward the north.
4 And charge the people, saying, Ye are going through the borders of your brethren the children of Esau, who dwell in Seir; and they shall fear you, and dread you greatly.
5 Do not engage in war against them, for I will not give you of their land even enough to set your foot upon, for I have given mount Seir to the children of Esau as an inheritance.
6 Buy food of them for money and eat, and ye shall receive water of them by measure for money, and drink.
7 For the Lord our God has blessed thee in every work of thy hands. Consider how thou wentest through that great and terrible wilderness: behold, the Lord thy God with thee forty years; thou didst not lack any thing.
