Matthew Chapter 5 Verse 4
μακάριοι οἱ πενθοῦντες, ὅτι αὐτοὶ παρακληθήσονται
blessed those who are mourning for they will be comforted
both verbs are εω verbs whose stems end in an e so they follow this contraction pattern ε + ω = ω ε + ει(ς) =εῖ(ς) ε + ο = οῦ etc.
πενθέω lament mourn grief here in 3rd person plural participle form
παρακληθήσονται is the future passive 3rd person plural of παρακαλέω
the same verb from which paraklete and para kleetos derive
summon call to help encourage exhort
however receiving help from the divine does not excuse us from our human obligations to try and help others so remember what is written in James about faith and works.
