Then shall the land enjoy her sabbaths, as long as it lieth desolate, and ye be in your enemies' land; even then shall the land rest, and enjoy her sabbaths.

Wesley's Notes

26:34 The land shall enjoy her sabbaths - It shall enjoy those sabbatical years of rest from tillage, which you through covetousness would not give it.

Jamieson-Fausset-Brown Bible Commentary

34. Then shall the land enjoy her sabbaths, as long as it lieth desolate, &c.-A long arrear of sabbatic years had accumulated through the avarice and apostasy of the Israelites, who had deprived their land of its appointed season of rest. The number of those sabbatic years seems to have been seventy, as determined by the duration of the captivity. This early prediction is very remarkable, considering that the usual policy of the Assyrian conquerors was to send colonies to cultivate and inhabit their newly acquired provinces.

Matthew Henry's Concise Commentary

26:14-39 After God has set the blessing before them which would make them a happy people if they would be obedient, he here sets the curse before them, the evils which would make them miserable, if they were disobedient. Two things would bring ruin. 1. A contempt of God's commandments. They that reject the precept, will come at last to renounce the covenant. 2. A contempt of his corrections. If they will not learn obedience by the things they suffer, God himself would be against them; and this is the root and cause of all their misery. And also, The whole creation would be at war with them. All God's sore judgments would be sent against them. The threatenings here are very particular, they were prophecies, and He that foresaw all their rebellions, knew they would prove so. TEMPORAL judgments are threatened. Those who will not be parted from their sins by the commands of God, shall be parted from them by judgments. Those wedded to their lusts, will have enough of them. SPIRITUAL judgments are threatened, which should seize the mind. They should find no acceptance with God. A guilty conscience would be their continual terror. It is righteous with God to leave those to despair of pardon, who presume to sin; and it is owing to free grace, if we are not left to pine away in the iniquity we were born in, and have lived in.
