2 Kings 10:6

Then he wrote a letter the second time to them
Having gained his point by the former:

saying, if ye be mine,
acknowledge yourselves my subjects and servants;

and if ye will hearken to my voice;
obey my commands:

take ye the heads of the men your master's sons;
that is, take off their heads:

and come to me to Jezreel by tomorrow this time
meaning with the heads along with them:

(now the king's sons, being seventy persons, were with the great men of
the city, which brought them up;)
they were in their houses, and under their tuition, and so had an authority over them, and could dispose of them at pleasure; they were not ordinary persons to whose care they were committed, but the principal men of the city.
