Following are a number of back-translations as well as a sample translation for translators of Hosea 13:2:

• Kupsabiny: “The people of Israel continue to sin to this day
  shaping/creating for themselves idols of silver.
  People shape those things
  in their empty/futile wisdom/skill.
  They say that those idols of calves are made for sacrifices
  and then they are kissed.” (Source: Kupsabiny Back Translation)
• Newari: “By making idols of metal they now sin more and more,
  they had craftsmen make idols of silver for themselves.
  The report of these people has been stated like this,
  "They offer human sacrifices
  and kiss the idol of the bull."” (Source: Newari Back Translation)
• Hiligaynon: “Now, you (plur.) who are-called Efraim continue doing-sin. For you (plur.) make images of little-gods/false-gods from your (plur.) silver so-that you (plur.) will-worship (them). But all these were only made by man and also according to just what he thought. You (plur.) still said that you (plur.) will-offer a person/man to these little-gods/false-gods which is a cow and kiss them.” (Source: Hiligaynon Back Translation)
• Kankanaey: “And now, they are making-worse their sin. Because those who are skilled metal-smiths, they are making their silver into false/imitation gods whose construction is carefully/well-done. They say, ‘Let’s sacrifice to them,’ while they kill those false/imitation gods of theirs that are imitation cows.” (Source: Kankanaey Back Translation)
• English: “Now they sin more and more;
  they make idols for themselves
  and coat the idols with their silver.
  Those idols are statues that are very cleverly made,
  but those statues are made by mere humans.
  But the people are told, ‘Kiss those idols that resemble a calf,
  and offer sacrifices to them!’” (Source: Translation for Translators)
