'Baptising' in the Bible

These things took place in Bethany, across the Jordan, where John was baptising.

and I knew him not; but that he might be manifested to Israel, therefore have I come baptising with water.

And John also was baptising in Aenon, near Salim, because there was a great deal of water there; and they came to him and were baptised:

and departed again beyond the Jordan to the place where John was baptising at the first: and he abode there.
