{Sought to touch him} (ez(8874)oun haptesthai autou).
Imperfect active. One can see the surging, eager crowd pressing
up to Jesus. Probably some of them felt that there was a sort of
virtue or magic in touching his garments like the poor woman in
 Lu 8:43f . ( Mr 5:23  Mt 9:21 ). {For power came forth from him}
(hoti dunamis par' autou ex(8872)cheto). Imperfect middle, {power
was coming out from him}. This is the reason for the continual
approach to Jesus. {And healed them all} (kai i(8374)o pantas).
Imperfect middle again. Was healing all, kept on healing all. The
preacher today who is not a vehicle of power from Christ to men
may well question why that is true. Undoubtedly the failure to
get a blessing is one reason why many people stop going to
church. One may turn to Paul's tremendous words in  Php 4:13 : "I
have strength for all things in him who keeps on pouring power
into me" (panta ischu(9320)en t(9369) endunamounti me). It was at a
time of surpassing dynamic spiritual energy when Jesus delivered
this greatest of all sermons so far as they are reported to us.
The very air was electric with spiritual power. There are such
times as all preachers know.
