72 (3rd/4th century) does show is that heurethēsetai is involved in the earliest attested reading, even though it is interpreted by the adverbial participle as including destruction. Readings involving the verb katakaiō have the best attestation next to heurethēsetai, but the textual witnesses supporting it tend to be later. aphanisthēsontai is only witnessed by one 5th century manuscript and so probably is not the original reading.
So we probably have to choose heurethēsetai as the original reading based on the quality of the witnesses and the fact that it is the more difficult reading. The negated verb form ouch heurethēsetai only occurs in some Syriac and Coptic manuscripts and as Bauckham (Jude, 2 Peter Word Biblical Commentary, 317) indicates is properly an emendation, using the negative ouch, which he suggests “yields such excellent sense that it must be considered the best solution unless the reading heurethēsetai can be given a satisfactory interpretation.” The problem is that the simple verb heurethēsetai seems to make little sense in the context. Some suppose that the clause should be punctuated as a question, i.e., “Will the earth and the things in it be found/discovered?”. This is possible, but seems to be somewhat forced. And then many scholars have proposed diverse emendations as the original reading, but none have found much support among other commentators.
Given the general theme of judgment which frames 3:10-13, it is possible that the verb form heurethēsetai “will be found/discovered” may have a sense of exposure, i.e., the real nature or character of the subject will become clear. The verb form is passive and it is quite possible that the agent, which is implied, is God himself. Through the destruction process God will expose “earth and the products/works in it” for what they have become — fallen, sin-filled and under Satan’s influence. The destruction then in itself is an act of judgment which results in “earth and the products/works in it” finally “being found” wanting, i.e., not measuring up to God’s righteousness.
This verb occurs again in 3:14 in connection with people embracing the gospel so that they “make every effort to be found (heurethēnai) spotless, blameless and at peace with him” (see also 1 Peter 1:6-8). Having said this, however, I would hasten to emphasize that the language used by the author does not indicate a refining or purifying of “earth and the products/works in it,” but rather their destruction. As well, it is possible the “earth and the products/works in it” are to be viewed as God’s creation and thus owned by him. The writer reminds us that God in the past destroyed the world, i.e., his creation, by water. Now the writer affirms that it will happen again and God will use fire as the means. However, it seems that the destruction is much more complete, clearing the way for “new heaven and new earth” (3:13; see Revelation 21:1). So perhaps we should translate 3:10d in this way: “and earth and the products/works in it will be discovered, i.e., exposed by God in their true, sin-marred nature and so destined to be destroyed.”
