Following are a number of back-translations as well as a sample translation for translators of Hosea 5:3:

• Kupsabiny: “I know the people of Ephraim
  and those of Israel are not lost to me.
  You have committed so much adultery, oh, Ephraim
  and put on yourselves dirt, oh, people of Israel.’” (Source: Kupsabiny Back Translation)
• Newari: “I know everything about Ephraim,
  Israel is not being hidden from me.
  You, O Ephraim, have been committing prostitution.
  Israel has defiled itself.” (Source: Newari Back Translation)
• Hiligaynon: “I know all about you (plur.) who come-from-Israel; you (plur.) can- not -hide- (anything) from me. You (plur.) worship little-gods therefore you (plur.) became unclean/dirty.” (Source: Hiligaynon Back Translation)
• English: “I know everything about the people of Israel;
  nothing that they have done is hidden from me.
  Because the people of Israel have given themselves to worshiping idols
  like prostitutes give themselves to the men they sleep with,
  they have become unacceptable to me.” (Source: Translation for Translators)
