The baptism of the Spirit was not very strong and did not last long, necessitating a re-baptism every few days. The Baptism of the Holy Spirit was a promise, not a command. There are two distinct differences between truths, commands, promises, and blessings. Truths are to be believed. Commands are to be obeyed.
Promises are to be received, and blessings are to be enjoyed.
The Holy Spirit Baptism John Said Christ would baptize, etc. Luke is not giving an account of all 120 disciples who happened to be in Jerusalem, so in accounting for the actions of the apostles, he throws the entire number of disciples in within parentheses in verse 15. Luke inserts into his account of the apostles' actions in those days a quotation made by Peter in verses 15 through 22. In verse 26, Luke again picks up the account of the apostles' doings in Jerusalem, and states that Matthias was numbered with the eleven, which made twelve called apostles in all. Of course, chapters and verses were added by men to help make Bible references easier.
