New Defender's Study Bible Notes
25:7 covering cast over all people. This “covering” and “vail” probably refers to the death shroud, which eventually covers every face. This will be removed in the coming resurrection.
25:7 spread over all nations. Despite the widespread human opinion that every nation has its own religion and should be encouraged to practice it, the Bible clearly teaches—here and elsewhere—that all nations are blinded, cut off from God’s truth by a deadly veil. Satan, the “god of this world hath blinded the minds of them which believe not” (II Corinthians 4:4). Only when the true saving gospel of Christ reaches their minds and hearts, then that “vail is done away in Christ” (II Corinthians 3:14).
