Washing is the cleansing of the body or hands and may include ceremonial ablution. In the New Testament context, the term especially concerns traditional handwashing before eating.
The disciples were criticized for eating with unwashed hands according to established tradition. Jesus contrasted these multiplied ceremonial precepts with God’s commandment and condemned treating human tradition as equivalent to divine authority.
People commonly used their fingers when eating from a shared dish, making clean hands practical. Traditional washing involved detailed actions and had become regarded as a serious religious obligation, beyond washings required for definite causes.
