And the same John had his raiment of camel's hair, and a leathern girdle about his loins; and his meat was locusts and wild honey. [Matthew 3:4 KJV]
John's way of life and especially his years in the wilderness are hinted at in the very brief description giving by Matthew of John's clothing and diet.
The word for camel, gamal, in Hebrew is a homonym and refers to both a camel and a new born baby the concept being shared in those meanings of both camels and babies to drink copiously. The camel features prominently in Genesis 25 in association with the finding of a bride for Isaac, the whole incident an allegory of Christ and the Church, even down to the astonishing detail of camels, dropped from the narrative and (as it were) becoming eleven men whose feet are washed.
Thus the whole association of the camel is an association with John's ministry, the baptism of repentance wherein (as John the apostle accounts of it) the stone waterpots of Israel are filled up to the brim, whence the contents become wine fit for the "chief of three who reclines, archetricline".
Thus the filling of camels with water, an association in Genesis, and the filling of water pots to the brim are an integral part of the ministry John was sent to fulfil, the preparing of the way (by repentance) before the face of the Lord, Malachi 3:1-4.
That John wears a leathern girdle about his loins indicates that he does not go to others for his clothing. He is able, from resources separate from civilisation, to supply himself providentially.
This also for his diet. Locusts and wild honey are about the only thing available in a desert. And thus John survives, without the company of men, or women. He survives alone and he is supported by providence.
And such a man comes forth with a unique ministry.
Jesus says of John that no other begotten of woman is greater than he. (It is important to be aware of the wording regarding Jesus' birth which excludes Jesus from this category, the 'begetting' being within the virgin prior to delivery, unlike the other mentions in scripture where delivery results in begetting.)
No other begotten of woman was greater than this man who came out of the desert, supported only by God and his providence, to speak a 'thus saith the Lord' to all of Israel.
And the result ?
Multitudes flocked to the baptism of John. All Judaea and its environs came out. Fishermen left their businesses in Galilee (John and James, Peter and Andrew) to follow John, thence to be led to Jesus.
This was the result of a total dedication, a complete separation. John was, as the prophets of old - Isaiah, Daniel, Enoch, Samuel and all the prophets - separated by God from a corrupt and fallen Israel, and given a word to speak to them that was uncompromised, completely separate, untainted by either fear or favour, and was wholly of God alone.
And, not long after his showing to Israel, he was decapitated for his faithful witness to Herod 'It is not lawful for thee to have her.'
