[21:13] 1 sn The imagery means “pay no attention to” the cry for help or “refuse to help,” so it is a metonymy of cause for the effect.
[21:13] 2 sn “Cry” here would be a metonymy of effect for the cause, the cause being the great needs of the poor.
[21:13] 3 sn The proverb is teaching that those who show mercy will receive mercy. It involves the principle of talionic justice – those who refuse the needs of others will themselves be refused when they need help (so Luke 16:19-31).
[25:12] 4 sn This saying is another example of emblematic parallelism; the first half is the simile, and the second half makes the point from it: A wise rebuke that is properly received is of lasting value. The rebuke in the ear of an obedient student is like ornaments of fine jewelry.
[25:12] 5 tn The “ear of the listener” refers to the obedient disciple, the one who complies with the reproof he hears. Cf. KJV, ASV, NAB “an obedient ear.”
