The land will rest because the people have been sent into exile. There is no one to cultivate the land or take advantage of it. In this way the land is purified and is given the opportunity to recover. The phrase, The land…shall enjoy its Sabbaths,
is unique. The verb is normally used for God or man. Here, the land itself is personified.
34 Alors le pays jouira de ses sabbats, tout le temps qu'il sera dévasté et que vous serez dans le pays de vos ennemis; alors le pays se reposera, et jouira de ses sabbats.
