2 Samuel 15:10

Absalom sent spies. The word means "those who go hither and thither," and, as the object of such journeying would usually be. to gather information, the right translation often is "spies." Here there was no such purpose, nor were they to report to Absalom, but to disperse themselves everywhere, and, when the signal was given at Hebron, they were to endeavour to gather the people to Absalom's standard. Some simple minded commentators wonder how one trumpet could be heard throughout the land. It was heard only at Hebron, but the news of the proclamation would rapidly spread; and, though the rumour might be vague and confused, yet these emissaries, fully acquainted beforehand with its meaning, would turn it to Absalom's advantage, and urge the people to confirm the choice, made, as they would affirm, by the whole tribe of Judah. In such attempts everything depends upon gathering a powerful following at first; and usually a good deal of vigour and even force is necessary to make men take part in a revolt. But as the numbers swell, adherents readily flock in to what seems to be the winning side.
