Paul speaks of people obtaining many teachers as if it were putting them into a heap or pile. AT: "they will listen to many teachers who assure them that there is nothing wrong with their sinful desires" (See: [[rc://en/ta/man/translate/figs-metaphor]])
Paul speaks of people strongly wanting to hear something as if their ears itched and could only be satisfied if teachers taught them what they wanted to hear. AT: "who say only what they want so much to hear" (See: [[rc://en/ta/man/translate/figs-idiom]])
Paul speaks about people no longer paying attention as if they were physically turning away so they cannot hear. AT: "They will no longer pay attention to the truth" (See: [[rc://en/ta/man/translate/figs-metaphor]])
"Turn aside" here is an idiom for "change direction toward." AT: "they will change direction toward teachings that are not true" (See: [[rc://en/ta/man/translate/figs-idiom]]).
Paul wants his readers to think correctly about everything, and he speaks about them as if he wanted them to be sober, that is, not drunk with wine. AT: "think clearly" (See: [[rc://en/ta/man/translate/figs-metaphor]])
