The Hebrew Bible recounts an instance where the prophet Daniel engaged in a prolonged period of abstinence from food and certain luxuries. This period of self-denial spanned three weeks, or 21 days, and was undertaken in a spirit of humility and fervent prayer. It represents a deliberate act of devotion intended to seek divine understanding and intervention.
This sustained commitment highlights the seriousness of Daniel’s supplication. The historical context suggests that Daniel was deeply troubled by the vision he received, a vision concerning future events of great consequence for his people. The act of fasting, combined with prayer, was a traditional means of demonstrating sincerity, focusing spiritual energy, and seeking divine favor in times of distress or when seeking guidance.
