Over and over, like a Tune — The Pilgrim's Progress

Over and over, like a Tune-1
The Recollection plays-
Drums off the Phantom Battlements
Cornets of Paradise-

Snatches, from Baptized Generations-5
Cadences too grand
But for the Justified Processions
At the Lord's Right hand.
(F.406/J.367)
[1] Over, Recollection:: the Christian recollected his sins when he crossed the river.
[3] Drums:: he heard the trumpet before the gate to heaven.
[6] grand:: a grand procession to receive the pilgrims.

Here also, as they that stood by perceived, he was much in the troublesome thoughts of the sins that he had committed, both since and before he began to be a pilgrim.

When he shall come with sound of trumpet in the clouds, as upon the wings of the wind, you shall come with him; and when he shall sit upon the throne of judgment; you shall sit by him; yea, and when he shall pass sentence upon all the workers of iniquity, let them be angels or men, you also shall have a voice in that judgment, because they were his and your enemies. Also, when he shall again return to the city, you shall go too, with sound of trumpet, and be ever with him. ─ The Pilgrim's Progress by John Bunyan
