Then the lawless one will be revealed, whom the Lord will kill with the breath of his mouth, and bring to nothing by the brightness of his coming;
This victory of the word, therefore, will shew itself in this world, for the spirit of his mouth simply means the word, as it also does in Isaiah 11:4, to which passage Paul seems to allude. For the Prophet there takes in the same sense the scepter of his mouth, and the breath of his lips, and he also furnishes Christ with these very arms, that he may rout his enemies. This is a signal commendation of true and sound doctrine — that it is represented as sufficient for putting an end to all impiety, and as destined to be invariably victorious, in opposition to all the machinations of Satan; as also when, a little afterwards, the proclamation of it is spoken of as Christ’s coming to us.
