The Greek that is translated into English as “vain” or “in vain” in English is (back-) translated in various ways:
Guhu-Samane: “with the front teeth of their mouths they worship me” (“‘In vain’ caused puzzlement [because] why should their efforts to worship God produce no results, try as they may? [But the idiom] ‘with the front teeth of their mouths they worship me’ comes from the picture of one who is making a pretense at eating food, hence their deceit is apparent.’ Source: Ernest L. Richert in Notes on Translation December 1963: p. 4-7; reprinted in The Bible Translator 1965, p. 198ff. )

In American Sign Language it is translated with a combination of the signs for “following” plus the sign for “authority” to differentiate it from disciple. (Source: Ruth Anna Spooner, Ron Lawer)
“apostles” in American Sign Language, source: Deaf Harbor
In Hungarian Sign Language it is translated with a sign that shows the shape of the beard, based on the common and general visual representation of the apostles. This sign differs from the sign for a beard as used in colloquial language. The sign of the apostle does not originate from a specific biblical verse, but rather from the cultural context and later ecclesiastical tradition. “Do not cut the hair at the sides of your head or clip off the edges of your beard.” Lev 19:27. In the biblical era, wearing a beard was the default social and religious norm among Jewish men. The Apostle Peter is generally depicted with a short, curly, white beard. The Apostle Paul appears with a longer, pointed beard. The Apostle John is an exception, as he was the youngest disciple. In iconography, he is often the only one painted without a beard (as a youth) to emphasize his purity and age (see for instance at Transfiguration (icon)). (Source: Jenjelvi Biblia and Andrea Bokros)
