Bede : The ark of the covenant, which was inside the veil, … very suitably symbolizes the nature of [Christ's] humanity. The urn [containing] manna symbolizes the fullness of his divinity. The staff of Aaron symbolizes the indestructible power of his priesthood, [and] the tablets of the covenant symbolize that it is he who gave the law and will also give his blessing to those who fulfill the law. — Homilies on the Gospels 2.25
