My defence (η εμη απολογια). Original sense, not idea of apologizing as we say. See on Acts 22:1; Acts 25:16. Refers to what precedes and to what follows as illustration Rev 1. Corinthians 8:13.

To them that examine me (τοις εμε ανακρινουσιν). See on 1. Corinthians 2:15; 1. Corinthians 4:3. The critics in Corinth were "investigating" Paul with sharp eyes to find faults. How often the pastor is under the critic's spy-glass.
