"Note on Baptism in Ac. Baptism in water (such as John's) is distinguished from baptism with the Holy Spirit (i. 5, etc.). Those who receive the latter, however, may also be baptized in water (cf. xi. 16 with x. 47); and there is one example of people who had previously received John's baptism receiving Christian baptism as a preliminary to receiving the Spirit (xix. 3 ff.). John's was a baptism of repentance (xiii. 24; xix. 4), as was also Christian baptism (ii. 38), but as John's pointed forward to Jesus (xix. 4), it became obsolete when He came. Christian baptism followed faith in the Lord Jesus (xvi. 31 ff.); it was associated with His name (ii. 38; viii. 16, etc.), which was invoked by the person baptized (xxii. 16); it signified the remission (ii. 38) or washing away of sins (xxii. 16); sometimes it preceded (ii. 38; viii. 15 ff.; xix. 5), sometimes followed (x. 47 f.) the receiving of the Spirit." (F. F. Bruce. The Acts of the Apostles [Greek Text Commentary], London: Tyndale, 1952, p. 98, n. 1.)

This word should not be confused with baptô (911). The clearest example that shows the meaning of baptizo is a text from the Greek poet and physician Nicander, who lived about 200 B.C. It is a recipe for making pickles and is helpful because it uses both words. Nicander says that in order to make a pickle, the vegetable should first be 'dipped' (baptô) into boiling water and then 'baptised' (baptizô) in the vinegar solution. Both verbs concern the immersing of vegetables in a solution. But the first is temporary. The second, the act of baptising the vegetable, produces a permanent change.
