Mark 6:21
Finally the opportune time came. On his birthday Herod gave a banquet for his high officials and military commanders and the leading men of Galilee — the opportune time (eukairos, the good moment) that Herodias has been waiting for arrives through the social calendar rather than through political planning. The birthday banquet is attended by the most important men in Galilee — the presence of witnesses at the highest level of power means that whatever Herod promises publicly, he cannot easily revoke without losing face. The birthday celebration is the occasion Herodias needed.
