The word denotes petitioning or interceding, often in formal contexts. Paul urges prayers, intercessions, and thanksgivings for all people (1 Tim 2:1). God's word is sanctified through prayer and petition (1 Tim 4:5). Classical usage ranged from petitions to authorities to intercourse or conversation, but NT usage focuses on prayer and intercession. The term suggests formal, deliberate prayer rather than casual conversation, and often carries the sense of advocacy on behalf of others.
