John 13:33

Glorification for Jesus involved temporary separation from His believing disciples. Jesus used a tender term for His disciples that showed His strong affection for them as members of His family. "Little children" (Gr. teknia, dear children) occurs only here in the fourth Gospel, but John used it seven times in 1 John mirroring Jesus’ compassionate spirit (1 John 2:1; 1 John 2:12; 1 John 2:28; 1 John 3:7; 1 John 3:18; 1 John 4:4; 1 John 5:21; cf. Galatians 4:19). Death and ascension to heaven would separate Jesus from them.
