The Hebrew noun gearah means a rebuke or reproof, derived from the verb gaar (H1605, 'to rebuke'). It appears about 15 times in the Old Testament and is used for both human correction and — most powerfully — the divine rebuke by which God controls nature and enemies.
The most striking feature of gearah in Scripture is its cosmic scope. When God rebukes (gaar), seas part (Psalm 106:9), nations flee (Isaiah 17:13), and enemies are scattered (Psalm 80:16; Isaiah 66:15). The divine gearah is not a minor correction but an authoritative decree that rearranges reality. Psalm 76:6 shows that even the mightiest warriors are helpless before God's rebuke: 'At your rebuke, O God of Jacob, both horse and chariot lie still.' Jesus' calming of the storm in Matthew 8:26 is the New Testament fulfillment of this divine authority — He rebuked (epitimao) the wind and waves, demonstrating His divine identity. The disciples' question was exactly right: 'What kind of man is this? Even the winds and the waves obey him!' Human wisdom also employs the gearah: Proverbs 13:1 says a wise son heeds his father's instruction; it is the fool who scorns rebuke.
