But the LORD is with me as a mighty terrible one: therefore my persecutors shall stumble, and they shall not prevail: they shall be greatly ashamed; for they shall not prosper: their everlasting confusion shall never be forgotten.
Therefore my persecutors shall stumble, and they shall not prevail - as they hoped to do (Jeremiah 20:10; Jeremiah 15:20).
They shall not prosper - in their plot.
