"And I will bring the land (That is the land of Canaan.) into desolation: and your enemies who dwell therein (That is the Canaanites at this point in time.) shall be astonished at it." At what? The desolation. How unproductive a beautiful strip of land could become, could so completely fall apart. But God did it with earthquakes. He did it with pestilence. He did it with drought. It stopped raining. All right, so here it is all foretold almost 1,000 years ahead of time. Now verse 33:
"And I will scatter you among the heathen, and will draw out a sword after you: (In other words, there'd be tremendous loss of life.) and your land shall be desolate, and your cities waste. 34. Then (When Israel is out of the land and everything is destroyed, God says--) shall the land (the Promised Land, the land of Canaan) enjoy her Sabbaths,..."
Well, what was the Sabbath in Israel's history? They had to leave the land fallow every seventh year. From the time that they came in under Joshua, they had to leave it fallow. God said, "I'll give you enough extra on the sixth year and the first year that you won't miss it." But did they believe God? No. They kept on farming it. They kept on taking out the fruit. So God says it's going to get them. All right, here it is. So when they're out of the land, and there's no production, there's no farming, there's no fruit trees growing, "Then shall the land rest and enjoy her (What?) Sabbaths."
