||The curse [will come] if you do not obey the commandments of God your Lord, and you go astray from the path that I am prescribing for you today, following other gods to have a novel spiritual experience.
Vehakelalah im-lo tishme'u el-mitsvot Adonay Eloheychem vesartem min-haderech asher anochi metsaveh etchem hayom lalechet acharey elohim acherim asher lo-yedatem.
|to have a novel spiritual experience|
Literally, 'which you have not known;' see Deuteronomy 13:3, 13:7, 13:14. To 'know' God is interpreted as knowing Him in a mystical sense, especially among the Kabbalists. See 1 Chronicles 28:9. (cf. HaKethav VeHaKabbalah).
