Questions about Tehillim (Psalms)

[Director Michael]

As prayers, this is effective in a language one understands fluently, provided that it's a reliable translation from an Orthodox Jewish publishing company, like Artscroll or Kehot. There is also a translation of Tehillim (Psalms) on line from Judaica Press, with Rashi's explanations:

For a Noahide, the precept of prayer is not to recite words of Hebrew Scripture without understanding the meaning. Rather, it is to praise or thank G-d, or to ask Him to fulfill one's needs, according to one's understanding. Since those themes are found throughout all of the 150 chapters of Psalms, therefore the Psalms are ideal for a Noahide to incorporate into his prayers. But if the Noahide doesn't understand the words he is saying, then those words aren't accomplishing praise, thanks, or requests to G-d.
