Hisgalus 3:1-2

Orthodox Jewish Bible

3 And to the malach (angel) of the Kehillah in Sardis, write: These things says the One having the sheva ruchot of Hashem and the shevat hakokhavim (seven stars): I have da’as of your ma’asim, that nominally you are Chai (Alive) but you are [spiritually] niftar (deceased).

² Be shomer and regarding the things remaining and the things on the point of mavet, be chazakim (strong ones). For, I have not found your ma’asim mitzvot having been shleimim (complete) before Elohai.
