Then shall the land enjoy her Sabbaths - This Houbigant observes to be a historical truth - "From Saul to the Babylonish captivity are numbered about four hundred and ninety years, during which period there were seventy Sabbaths of years; for 7, multiplied by 70, make 490. Now the Babylonish captivity lasted seventy years, and during that time the land of Israel rested. Therefore the land rested just as many years in the Babylonish captivity, as it should have rested Sabbaths if the Jews had observed the laws relative to the Sabbaths of the land." This is a most remarkable fact, and deserves to be particularly noticed, as a most literal fulfillment of the prophetic declaration in this verse: Then shall the land enjoy her Sabbaths as long as it lieth desolate, and ye be in your enemies' land. May it not be argued from this that the law concerning the Sabbatical year was observed till Saul's time, as it is only after this period the land enjoyed its rest in the seventy years' captivity? And if that breach of the law was thus punished, may it not be presumed it had been fulfilled till then, or else the captivity would have lasted longer, i. e., till the land had enjoyed all its rests, of which it had ever been thus deprived?

This was fulfilled during the Babylonish captivity: for, from Saul to the captivity are about

490 years, during which period there were

70 sabbaths of years neglected by the Hebrews. Now the Babylonish captivity lasted

70 years, and during that time the land of Israel rested.

Approaching Doom
The first years of Jehoiakim's reign were filled with warnings of approaching doom. The word of the Lord spoken by the prophets was about to be fulfilled. The Assyrian power to the northward, long supreme, was no longer to rule the nations. Egypt on the south, in whose power the king of Judah was vainly placing his trust, was soon to receive a decided check. All unexpectedly a new world power, the Babylonian Empire, was rising to the eastward and swiftly overshadowing all other nations. Within a …

Leviticus
The emphasis which modern criticism has very properly laid on the prophetic books and the prophetic element generally in the Old Testament, has had the effect of somewhat diverting popular attention from the priestly contributions to the literature and religion of Israel. From this neglect Leviticus has suffered most. Yet for many reasons it is worthy of close attention; it is the deliberate expression of the priestly mind of Israel at its best, and it thus forms a welcome foil to the unattractive …
