2 Samuel 19:7

I swear by the Lord. — The statement which Joab emphasises with this solemn oath is not that ne will lead the people into revolt — he does not seem to have conceived, far less to have expressed any such design — but it is simply an assurance of the extreme danger of the course David was pursuing, put in such a strong and startling way as to rouse him from the selfishness of his sorrow.
