Following are a number of back-translations as well as a sample translation for translators of Jeremiah 25:3:

• Kupsabiny: “In the thirty three years that have passed since the thirteenth year of the rulership of Josiah son of Amon, the king of Judah until today, God has often (again and again) spoken to me and I have also spoken to you often, but you have not listened.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “For a period/[lit. inside] of 23 years — from the 13th year of Josia child/son of Amon reign in Juda until now — the LORD was-speaking to me. And I continue to tell you (plur.) what he is-saying, but you (plur.) did- not -listen at-all.” (Source: Hiligaynon Back Translation)
• English: “‘Yahweh has been giving me messages for 23 years. He started giving me messages when Josiah, the son of Amon, had been ruling Judah for almost 13 years. And I have faithfully told you those messages, but you have not paid any attention to them.” (Source: Translation for Translators)
