'Beside' in the Bible

And when his friends heard it, they went out to lay hold on him: for they said, He is beside himself.

For whether we are beside ourselves, it is unto God; or whether we are of sober mind, it is unto you.

Are they ministers of Christ? (I speak as one beside himself) I more; in labors more abundantly, in prisons more abundantly, in stripes above measure, in deaths oft.
