The Greek verb dialaleo means to speak about something widely, to spread by conversation, or to discuss broadly. It is a compound of dia (through/among) and laleo (to speak), suggesting thorough or widespread speaking.
In Luke 1:65, dialaleo describes how word of the miraculous events surrounding John the Baptist's birth spread throughout the hill country of Judea. The verb captures how God's extraordinary acts cannot be contained — they spread organically through human conversation. The Gospel itself spreads this way: not through institutional channels alone but through the spoken testimony of ordinary witnesses.
