The answer is: Dipped a piece of bread and passed it to him

Matthew 26:23 - a custom to take a piece of bread or meat wrapped in bread and dip it in a bowl of sauce.

In the scene of betrayal from Matthew 26, Jesus points out Judas Iscariot in a very intimate manner. By sharing bread, he not only acknowledges Judas as part of the group but emphasizes their connection. This gesture suggests that betrayal doesn't always come from cold severance; it can come from intimacy and friendship, making it even more poignant. Bread, in many cultures, symbolizes life and community, so this act contains a bittersweet contrast.

This moment takes place during the Last Supper, a feast rich in tradition. The act of dipping bread into a bowl for taste—or lazzat—has roots in many ancient culinary practices. In the Bible, bread often signifies sustenance and fellowship. The Manna in the wilderness is a great Old Testament echo, representing divinely provided nourishment for the Israelites. Jesus likens himself to the true Bread of Life, further intertwining the significance of bread across both testaments.

The depth of this moment highlights that even in the face of betrayal—an action that would lead to his crucifixion—Jesus still demonstrates grace and a hopeful call for reconciliation. This echo of God's unyielding love offers a lesson to illuminate our own choices of loyalty and betrayal, urging us to reflect on the deeper meaning of relationships—especially those that lie within an intimate circle. It’s an invitation to choose love even when confronted with disloyalty.
