John Lightfoot on Matthew 3:5

[The region round about Jordan.] The word the region round about, is used by the Jerusalem Gemara: "From Beth-horon to the sea is one region round about," or, one circumjacent region. Perhaps, both in the Talmudist and in the evangelist, is one and the same thing with a coast, or a country along a coast, in Pliny: "The country (saith he) along the coast is Samaria": that is, the sea-coast, and the country further, lying along by that coast: which may be said also concerning the region round about Jordan. Strabo, concerning the plain bordering on Jordan, hath these words; "It is a place of a hundred furlongs, all well watered and full of dwellings."

A few things concerning Baptism.
