² tn Or “branded.” The Greek verb καυστηριάζω (kaustēriazō) can be used to refer either to the cause (“brand”) or the effect (“seared”).

² sn Consciences are seared. The precise meaning of this phrase is somewhat debated. Three primary interpretations are (1) the consciences of these false teachers are “branded” with Satan’s mark to indicate ownership, (2) their consciences are “branded” with a penal mark to show they are lawbreakers, or (3) their consciences have been “seared” (i.e., totally burnt and desensitized) so that they are unable to notice the difference between right and wrong. See G. W. Knight, Pastoral Epistles (NIGTC), 189.

¹ sn The imagery of the “burning coals” represents pangs of conscience, more readily effected by kindness than by violence. These coals produce the sharp pain of contrition through regret (e.g. 18:19; 20:22; 24:17; Gen 42-45; 1 Sam 24:18-20; Rom 12:20). The coals then would be an implied comparison with a searing conscience.
