On many occasions the angels could have given their names. Noah asked the angel what is your name. The good angel never gave his name. Because of their humility they do not want the honor.
Because of humility perfect heavenly angels who are in the presence of God Himself and Jesus do not give their names or accept worship it is said. Contrast that with the way the governing body, their "helpers" and any other hangers on put their mugs out there on governing body TV and at assemblies. Wanting to be seen by men. Wanting their names memorized. Wanting the front seats in the synagogues.
