{They were willing therefore} ((8874)helon oun). Inchoative
imperfect, "they began to be willing." This does not contradict
 Mr 6:51  as Bernard thinks. Both Jesus and Peter climbed into
the boat. {Whither they were going} (eis h(886e) hup(8867)on).
Progressive imperfect active, "to which land they had been going"
(intransitive use of hupag(935c), to lead under, to go under or away
as in verse  67  7:33  12:11  18:8 .
