Hebrews 12:27

Signifieth the removing. The phrase “yet once more” implies that the second shaking is to be final. No further shaking will be required. Accordingly, whatever can be shaken will be removed at the time of the second shaking.

That are shaken. That is, that can be shaken. Sin and all its works will be “shaken.” This present world and all that is in it will pass away.

As of things that are made. The relationship of this clause to the line of thought is not readily apparent. The Greek is brief and cryptic. The writer may be alluding to the fact that as God spoke the heavens and the earth into being at the beginning (see on Genesis 1:3; Hebrews 11:3; cf. Psalm 33:6, 9), so He will speak again to remove all that can be shaken.

Things which cannot be shaken. That is, the “kingdom which cannot be moved” (verse 28), including all “just men made perfect” (verse 23).

May remain. When God’s voice again shakes heaven and earth only that which is right and pure and true will remain.
