So one of my favorite Jewish artists is Debbie Friedman. Every week we lift up those who are in need of healing and then we sing this song.

The English and Hebrew are interchanged letting you know what is being sung. In my synagogue we do not have instruments on Saturday so everything is sung/chanted acapella. On Friday nights we occasionally do have instruments and music.
