Mark 1:6

(Moral. xxxi. 25) Or, by the kind itself of his food he pointed out the Lord, of whom he was the forerunner; for in that our Lord took to Himself the sweetness of the barren Gentiles, he ate wild honey. In that He in His own person partly converted the Jews, He received locusts for His food, which suddenly leaping up, at once fall to the ground. For the Jews leaped up when they promised to fulfil the precepts of the Lord; but they fell to the ground, when by their evil works they affirmed that they had not heard them. They made therefore a leap upwards in words, and fell down by their actions.

It says, clothed in a garment of hair, not in woollen clothes; the former is the mark of an austere garb, the latter of effeminate luxury. But the girdle of skins, with which he was girt, like Elias, is a mark of mortification. And this meat, locusts and wild honey, is suited to a dweller in the wilderness, so that his object in eating was not the deliciousness of meats, but the satisfying of the necessity of human flesh.

(ubi sup.) The dress and food of John may also express of what kind was his inward walk. For he used a dress more austere than was usual, because he did not encourage the life of sinners by flattery, but chid them by the vigour of his rough rebuke; he had a girdle of skin round his loins, for he was one, who crucified his flesh with the affections and lusts. (Gal. 5:24) He used to cat locusts and wild honey, because his preaching had some sweetness for the multitude, whilst the people debated whether he was the Christ himself or not; but this soon came to an end, when his hearers understood that he was not the Christ, but the forerunner and prophet of Christ. For in honey there is sweetness, in locusts swiftness of flight; whence there follows, And he preached, saying, there cometh one mightier than I after me.

Or else; The garment of camel's hair was significative of grief, for John pointed out, that he who repented should mourn. For sackcloth signifies grief; but the girdle of skins shows the dead state of the Jewish people. The food also of John not only denotes abstinence, but also shows forth the intellectual food, which the people then were eating, without understanding any thing lofty, but continually raising themselves on high, and again sinking to the earth. For such is the nature of locusts, leaping on high and again falling. In the same way the people ate honey, which had come from bees, that is, from the prophets; it was not however domestic, but wild, for the Jews had the Scriptures, which are as honey, but did not rightly understand them.

The dress of John, his food, and employment, signifies the austere life of preachers, and that future nations are to be joined to the grace of God, which is John, both in their minds and in externals. For by camel's hair, is meant the rich among the nations; and by the girdle of skin, the poor, dead to the world; and by the wandering locusts, the wise men of this world; who, leaving the dry stalks to the Jews, draw off with their legs the mystic grain, and in the warmth of their faith leap up towards heaven; and the faithful, being inspired by the wild honey, are full-fed from the untilled wood.
