And they show devotion to me in vain, teaching as doctrine the commandments of men.a Bible other translations
From Isa. 29:13

“doctrine.” The Greek word is didaskalia (#1319 διδασκαλία), a noun, and it has two primary meanings: It is used of the act of teaching or instruction (as if it was a verb), and it is also used for what is taught, i.e., the doctrine or material that was presented. In this verse we felt “doctrine” was better than “teaching.” For more on didaskalia see commentary on 1 Tim. 4:13).
