To strike or smite, when used in the Bible, means to attack, harm or destroy, and is usually in reference to an attack on someone's knowledge and intellect. This is actually true both when evil people strike good people, trying to destroy their understanding of spiritual things, and when the Lord is pictured as striking people (with plagues in Egypt, for example), which most often represents the dulling of the intellect and destruction of knowledge in evil people to prevent them from doing spiritual harm to others.

6765. 'And he said to the one in the wrong, Why are you striking your companion?' means a rebuke, deploring that one person should wish to destroy another's faith. This is clear from the meaning of 'the one in the wrong' as a person who does not uphold the truth of faith and yet is within the Church (for within the Church there are those who uphold the truth of faith and there are those who do not, as the existence of various heresies goes to prove; and those who subscribe to heresy, that is, who do not uphold the truth of faith, are meant here by 'the one in the wrong'); from the meaning of 'striking' as destroying, as above in 6758; and from the meaning of 'companion' as a person who upholds the truth of faith. For when 'the one in the wrong' means a person who does not uphold the truth of faith, 'companion' means one who does uphold it. The word 'companion' is used, not 'brother', even though both of them were Hebrews, because they were hostile to each other. The fact that this is a rebuke is self-evident. What all this implies is that when a person is being regenerated he is sent into battles against falsities. During these the Lord maintains him in truth, but in what he has convinced himself to be the truth; and this is what is used in the battles against falsity. Even that which is not the real truth can be used, provided that it is such as can in some way be joined to good. And it is joined to good through innocence, for innocence is the means which enables that conjunction to be effected. This explains why people within the Church who have accepted any teaching whatever can be regenerated, though those who are in possession of real truths are in a better position than others.
