Following are a number of back-translations as well as a sample translation for translators of Isaiah 8:14:

• Kupsabiny: “God is a house of life
  for righteous people.
  But he is a stone that that makes (people) stumble/fall
  and make people crash/fall.
  He will cause the people of Israel and Judah to fall,
  and (he is) a snare that catches the people of Jerusalem.” (Source: Kupsabiny Back Translation)
• Newari: “He will be in the place where you live,
  but as for Israel, Judah and Jerusalem, he will be a rock.
  and people will stumble on that rock and fall down.
  He will be like a trap to capture them,” (Source: Newari Back Translation)
• Hiligaynon: “I will-be your (plur.) place-of-refuge. But for Israel and Juda, I am like a rock that causes- (them) -to-stumble and makes- them -fall, and for the people of Jerusalem, I am like a trap/snare.” (Source: Hiligaynon Back Translation)
• English: “I will protect you(sg).
  But as for the other people in Israel and Judah,
  I will be like a stone that causes people to stumble,
  a rock that causes them to fall down.
  And as for the people of Jerusalem,
  I will be like a trap or a snare.” (Source: Translation for Translators)
