4:38 Who were the other labourers Jesus refers to here?

(CP V36-37). The other labourers included Jesus Himself and John the Baptist, plus the Old Testament prophets.

The disciples had already healed many and baptized many as well (CP Mt 10:1, 5-8; Lu 9:1-2; 10:1-2; Jn 4:1-2).

4:46-52 See comments on Jn 2:23-25.
