Deuteronomy 4:30 - Joseph Benson’s Commentary on the Old and New Testaments

In the latter days Either in general in succeeding ages and generations, or particularly in the days of the Messiah, commonly called in Scripture, the latter, or last days. Here the apostacy and misery of the Jewish nation in the latter days is clearly foretold, as it is more at large in chap 28. But the passage also gives encouragement to hope for their conversion and redemption; and that even in those times when their case should seem most desperate; when they should have forsaken God and rejected the Messiah, toward the end of the world.
