John Trapp on Matthew 26:16

Verse 16. And from that time he sought] So it was no sudden but a prepensed wickednesse, done in cold blood, and upon mature deliberation. Gods people when they sinne, they are preoccupated, and taken before they are aware, Gal. 6. 1. There isPsal 139 ult. no way of wickednesse in them, ordinarily. It is of incogitancy: put them in minde, and they mend all. Or it is of passion; and passions last not long. They deny not Christ that bought them: they can do nothing against the truth, they will not fongoe God upon any tearms, they never sinne with deliberation about this chief end: if they erre, it is only in the way, as thinking that they may fulfill such a lust, and keep God too.
