Paul speaks of people obtaining many teachers as if they were putting them into a heap or pile. Alternate translation: "they will listen to many teachers who assure them that there is nothing wrong with their sinful desires" (See: [[rc://en/ta/man/jit/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. Alternate translation: "who say only what they want so much to hear" (See: [[rc://en/ta/man/jit/figs-idiom]])
