Mark 1:4

John did baptize in the wilderness,.... Of Judea, Mt 3:1, where he first appeared as a preacher; and is the same wilderness Isaiah has respect to in the above prophecy, Isa 40:3. The words are best rendered in the Vulgate Latin and Syriac versions; "John was in the wilderness, baptizing and preaching the baptism of repentance, for the remission of sins": according to which, the account of the Baptist begins with his name, John; describes the place where he was where he made his first appearance, and continued in, the wilderness; which was not a wild uninhabited place and without people, but had many cities, towns, and villages in it; and also declares his work and ministry there, which was preaching and baptizing: for though baptizing is here put before preaching, yet certain it is, that he first came preaching in these parts; and there baptized such, to whom his preaching was made useful.
