Matthew Poole and continuators on Mark 1:5

5. And there went out unto him all the land of Judea, and they of Jerusalem, and were all baptized of him in the river of Jordan, confessing their sins.

Luke saith that Iohn began about the fifteenth year of Tiberius Caesar, he Baptized in the Wilderness, that is a place little inhabited, by his Baptism is not to be strictly understood Baptism, b[illegible: 1 letter]t his Preaching and Doctrine, his whole Administration, which is called the B[illegible: 1 letter]ptism of Repentance, because Repentance was the great thing he Preached▪ a seal of which Baptism was to be, the consequent of which was to be the Remission of Sins, or the Argument which he used to press Repentance, was the Remission of Sins. See further the Annotations on Matth. 3.5.6. where we before had these Words.
