'Eating' in the Bible

But when the Scribes of the Pharisee sect saw Him eating with the sinners and the tax-gatherers, they said to His disciples, "He is eating and drinking with the tax-gatherers and sinners!"

They had noticed that some of His disciples were eating their food with 'unclean' (that is to say, unwashed)

And while they were at table Jesus said, "I solemnly tell you that one of you will betray me--one who is eating with me."
