And they sent their disciples to him along with the Herodians, saying, “Teacher, we know that you are true (alēthēs | ἀληθής | nom sg masc) and teach the way of God in truth, and show deference to no one, for you are not swayed by appearances.
Everyone has testified favorably regarding Demetrius, and so has the truth (alētheias | ἀληθείας | gen sg fem) itself. And we testify for him as well, and you know that our testimony is true.
For I rejoiced greatly when the brothers came and testified to your fidelity to the truth (alētheia | ἀληθείᾳ | dat sg fem), as indeed you do walk in the truth (alētheia | ἀληθείᾳ | dat sg fem).
I rejoiced greatly because I have found some of your children walking in the truth (alētheia | ἀληθείᾳ | dat sg fem), just as we received commandment from the Father.
Grace, mercy, and peace will be with us, from God the Father and from Jesus Christ the Son of the Father, in truth (alētheia | ἀληθείᾳ | dat sg fem) and in love.
