may be in you, might remain in you

The Greek that is translated in English as “(my joy) might remain in you” or “(my joy) may be in you” is translated in Tzotzil as “these things I have told you in order that your hearts may be happy-untroubled like my heart is happy-untroubled.”

“If Jesus’ words in John 15:11 were to be translated literally (…) it would infer that Jesus had given all His joy away and so not have any Himself.” (Source: Marion Cowan in The Bible Translator 1963, p. 90)
