Following are a number of back-translations as well as a sample translation for translators of Isaiah 55:5:

• Kupsabiny: “You (plur.) shall call/summon people of nations that you do not know,
  and nations that do not know you shall run to you.
  It shall be like that on account of your God,
  the righteous God of Israel
  because he is raising you up.’” (Source: Kupsabiny Back Translation)
• Newari: “You will summon [lit.: call hither] nations [you] do not know,
  and nations you do not know will come in a hurry.
  because I, the LORD your God, the Holy One of Israel,
  have made you glorious.’” (Source: Newari Back Translation)
• Hiligaynon: “You (plur.) will-call the nations which are not your (plur.) companion, and they will-hurry to go to you (plur.) because I, the LORD your (plur.) God, the Holy God of Israel, have-honored you (plur.).” (Source: Hiligaynon Back Translation)
