Isaiah 55:3 calls to 'incline your ear and hear' — a parallel invitation to listen and receive life from God.

Mark 4:9 uses Jesus' common exhortation 'He who has ears to hear, let him hear,' emphasizing the call to listen as in Matthew 15:10.

Acts 8:30 records Philip asking the eunuch if he understands what he reads, paralleling Jesus' call to 'hear and understand'.
