New Defender's Study Bible Notes
9:27 once to die. Enoch and Elijah seem to have been exceptions to this principle (Genesis 5:24; II Kings 2:11), but they will probably return to the earth in the last days, and then die (see notes on Revelation 11:3-12). There will be one great exception, of course, for the saints living on earth when Christ returns (I Corinthians 15:51-53), but all (even those who will be living at that time) must prepare for death, for no one can be sure he will not die before Christ comes.
9:28 bear. “Bear” here is the same word as “offer up” in Hebrews 7:27. Christ not only bore the penalty of our sins on the cross, but also offered up His sacrificial blood to the Father as proof thereof (contrast Hebrews 9:24-25). Israel’s high priest offered up the blood of animals as an atonement for sins. Our High Priest offered up Himself!
9:28 look for him. To “look for Him” means to “expectantly wait for Him,” knowing that He might come at any time. There is nothing in the whole scope of prophesied events in the last days that must be fulfilled before He comes. Many of these events could happen before His return, but none must happen. We should “look for Him” every day and “love His appearing” (II Timothy 4:8).
