The reading is from 2 Timothy and is this passage starting at verse 2: -
2 Tim 4:1-5: - Preach the Word
4:1 I charge you therefore before God and the Lord Jesus Christ, who will judge the living and the dead at His appearing and His kingdom: 2 Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching. 3 For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers; 4 and they will turn their ears away from the truth and be turned aside to fables. 5 But you be watchful in all things, endure afflictions, do the work of an evangelist, fulfill your ministry.
NKJV
Verse 3 is the warning where it talks about "they will heap up for themselves teachers;". What Paul is saying is that the Saints will fall away not enduring sound teaching and will accumulate teachers for themselves who will satisfy their itching ears.
