As long as it lieth desolate, it shall rest— "This," says Houbigant, "is literally and historically true. From Saul to the Babylonish captivity, 490 years are commonly numbered; in which period of time were 70 sabbaths of years; for 7 multiplied by 70 makes 490: but the Babylonish captivity continued 70 years, during which the land of Israel rested: therefore the land rested in that captivity so many years as it ought to have rested sabbaths, if the Jews had observed the law respecting the rest of the land."
