In Genesis 13, we read:
One of the misconceptions by people who have never traveled to Israel is that the entire land is a dry, barren wasteland. And, while there are portions of the land that are very dry (notably, the wilderness areas south of the Negeb), much of the land is green, lush, and vibrant with life.
In the passage that I mentioned above, Abraham gives Lot the choice of the piece of land he wants to settle. Lot gazes down into the "well watered" Jordan Valley and decides to locate his family in this region. As you can see from the picture, this land is still agriculturally rich and crops are still grown in this region.
(NOTE: Looking at the picture, you would think that the Jordan River would be visible. In reality, it is not. The river flows through the center of the Jordan Rift Valley, but sits very low and it not visible most time of the year.)
