The עָרִיצִים ('aritsim) are tyrants, the people who inspire fear (Job 15:20; 27:13); the root verb עָרַץ ('arats) means “to terrify” (Job 13:25).
The NET translation
Or ‘Deliver me from the enemy’s power, and from the hand of tyrants ransom me’?
It’s exactly why I really like the NET translation. Getting context for why or how the original text gets translated to English is incredibly valuable to me. Here in this context I’m sure aritsim doesn’t literally mean tyrant, but the people became synonymous with the definition like “Shaka, when the walls fell” means failure.
