On Jesus’ breast; the same as in Jesus’ bosom. Or, he lay first in Jesus’ bosom, and then ascended higher, and lay upon His breast; as if, had he remained lying in His bosom, and not ascended to lie on His breast, our Lord would not have told him what Peter wanted to know. By his lying at last on Jesus’ breast, is expressed that greater and more abundant grace, which made him Jesus’ special disciple.
