1 John 2:26

2:26 These things I have written to you about those who are trying to deceive you. ¹ 

1 John 5:21

5:21 Little children, guard yourselves from idols. ² 

[2:26]  ¹ sn The phrase those who are trying to deceive you in 1 John 2:26 is a clear reference to the secessionist opponents mentioned earlier in 1 John 2:19, who are attempting to deceive the people the author is writing to.

[5:21]  ² tc Most later mss (P Ï) have ἀμήν (amhn, “amen”) at the end of this letter. Such a conclusion is routinely added by scribes to NT books because a few of these books originally had such an ending (cf. Rom 16:27; Gal 6:18; Jude 25). A majority of Greek witnesses have the concluding ἀμήν in every NT book except Acts, James, and 3 John (and even in these books, ἀμήν is found in some witnesses). It is thus a predictable variant. Further, the earliest and best witnesses, along with several others (א A B Ψ 33 323 630 1505 1739 al sy co), lack the inoffensive particle, rendering its omission as the authentic reading.
