Acts 5:37

And after this man rose up Judas of Galilee in the days of the enrollment, and drew away some of the people after him: he also perished; and all, as many as obeyed him, were scattered abroad.

Judas ... was said to have been "of Galilee," because that was the seat of his insurrection against Rome; he was also called the Gaulonite, derived from Gamala, his native city in Gaulonitis.

The days of the enrollment ... Gamaliel mentioned this, not, because of the enrollment that led to the birth in Bethlehem, but because Judas "was the leader of the Jewish uprising which opposed the census ordered by Augustus, after the deposition of Archelaus."[44] The enrollment here, as well as the one that led to Joseph and Mary's trip to Bethlehem, was also carried out by Quirinius.

The point, exactly like that in the narration about Theudas, was that God did not bless the insurrection; and, therefore, it failed.
