These ringing notes are parts of a highly poetic picture of that great deliverance which inspired this prophet's most exalted strains. It is described with constant allusion to the first Exodus, but also with significant differences. Now no doubt the actual historical return of the Jews from the Babylonish captivity is the object that fills the foreground of this vision, but it by no means exhausts its significance. The restriction of the prophecy to that more immediate fulfilment may well seem impossible when we note that my text follows the grand promise that 'all the ends of the earth shall see the salvation of our God,' and immediately precedes the Messianic prophecy of the fifty-third chapter. Egypt was transparent, and through it shone Babylon; Babylon was transparent, and through it shone Christ's redemption. That was the real and highest fulfilment of the prophet's anticipations, and the trumpet-calls of my text are addressed to all who have a share in it. We have, then, here, under highly metaphorical forms, the grand ideal of the Christian life; and I desire to note briefly its various features. I. First, then, we have it set forth as a march of warrior priests. Note that phrase--'Ye that bear the vessels of the Lord.' The returning exiles as a whole are so addressed, but the significance of the expression, and the precise metaphor which it is meant to convey, may be questionable. The word rendered 'vessel' is a wide expression, meaning any kind of equipment, and in other places of the Old Testament the whole phrase rendered here, 'ye that bear the vessels,' is translated 'armour-bearers.' Such an image would be quite congruous with the context here, in which warlike figures abound. And if so, the picture would be that of an army on the march, each man carrying some of the weapons of the great Captain and Leader. But perhaps the other explanation is more likely, which regards 'the vessels of the Lord' as being an allusion to the sacrificial and other implements of worship, which, in the first Exodus, the Levites carried on the march. And if that be the meaning, as seems more congruous with the command of purity which is deduced from the function of bearing the vessels, then the figure here, of course, is that of a company of priests. I venture to throw the two ideas together, and to say that we may here find an ideal of the Christian community as being a great company of warrior-priests on the march, guarding a sacred deposit which has been committed to their charge.
