Whoever has ears to hear, let him hear

Jesus is emphasizing that what he has just said is important and may take some effort to understand and put into practice. The phrase "has ears" is a metonym for being willing to understand and obey. Alternate translation: "Whoever is willing to listen, listen" or "Whoever is willing to understand, let him understand and obey" (See: rc://en/ta/man/jit/figs-metonymy)

Whoever has ... let him hear

Since Jesus wanted his audience to pay attention, this can also be expressed with the word "you." Alternate translation: "If you have ears to hear, then hear" or "If you are willing to understand, then understand and obey" (See: rc://en/ta/man/jit/figs-123person)
