Mark 4:9 earlier calls 'he who has ears to hear' — reinforcing the exhortation to listen carefully.

In Matthew 7:2, the same 'measure you use' principle applies to judgment, expanding Jesus' warning beyond hearing to judging.

Luke 6:38 repeats the measure saying, applied to giving — directly echoing the same principle of generous return.

Luke 8:18 parallels this with 'take care how you hear' and the same measure principle — a stronger warning about hearing.

Hebrews 2:1 explicitly urges paying closer attention to what was heard — directly echoing Mark's warning.

Matthew 13:12 parallels the same principle: proportional reward and loss based on what one has.

Romans 10:17 shows faith comes through hearing — adds why paying attention to what you hear matters.

2 Corinthians 9:6 uses sowing/reaping imagery to illustrate the same proportional return — a different metaphor, same principle.
