John Gill Bible Commentary

Then shall the land enjoy her sabbaths,.... The sabbatical years, or seventh year sabbaths, when, according to the law in the preceding chapter, it was to rest from tillage, Lev 25:2, as long as it lieth desolate, and ye be in your enemies' land; so long it should lie uncultivated, at least in part, there not being a sufficient number left to till it in general, or as it should be; this was the case during the seventy years' captivity in Babylon: even then shall the land rest, and enjoy her sabbaths; or complete them, as Aben Ezra, which is a bitter sarcasm upon them for their neglect of observance of the law concerning the sabbatical years; but now the land should have its sabbaths of rest whether they would or not; and it seems as if it was on account of this sin, as well as others, that they were carried captive; and it is remarkable, if what Maimonides (x) says is right, that it was at the going out or end of a sabbatical year, that the first temple was destroyed, and the Jews carried captive, and endured a seventy years' captivity; which some say was because they had neglected seventy sabbatical years; see Ch2 36:21. (x) Hilchot Shemitah Vejobel, c. 10. sect. 3.
