Deuteronomy 12:10

But when ye go over Jordan, and dwell in the land which the Lord your God giveth you to inherit, and when he giveth you rest from all your enemies round about, so that ye dwell in safety;
8

Ye shall not do after all the things that we do here this day, every man whatsoever is right in his own eyes.

9

For ye are not as yet come to the rest and to the inheritance, which the Lord your God giveth you.

10

But when ye go over Jordan, and dwell in the land which the Lord your God giveth you to inherit, and when he giveth you rest from all your enemies round about, so that ye dwell in safety;

11

Then there shall be a place which the Lord your God shall choose to cause his name to dwell there; thither shall ye bring all that I command you; your burnt offerings, and your sacrifices, your tithes, and the heave offering of your hand, and all your choice vows which ye vow unto the Lord:

12

And ye shall rejoice before the Lord your God, ye, and your sons, and your daughters, and your menservants, and your maidservants, and the Levite that is within your gates; forasmuch as he hath no part nor inheritance with you.

Counter-Arguments

The strongest case that this verse does not belong in this theme.

Land Sabbath / Rest for the Earth

The verse speaks of the people dwelling in the land and receiving rest from their enemies, not of the land itself resting or being subject to cycles of fallow periods. The "rest" mentioned here refers to the security and peace of the inhabitants, not an agricultural practice or a Sabbath for the earth.
