2 Samuel 17:6 (KJV)

Moreover Ahithophel said unto Absalom, Let me now choose out twelve thousand men, and I will arise and pursue after David this night:

And I will come upon him while he is weary and weak handed, and will make him afraid: and all the people that are with him shall flee; and I will smite the king only:

And I will bring back all the people unto thee: the man whom thou seekest is as if all returned: so all the people shall be in peace.

And the saying pleased Absalom well, and all the elders of Israel.

Then said Absalom, Call now Hushai the Archite also, and let us hear likewise what he saith.

And Hushai said unto Absalom, The counsel that Ahithophel hath given is not good at this time.

For, said Hushai, thou knowest thy father and his men, that they be mighty men, and they be chafed in their minds, as a bear robbed of her whelps in the field: and thy father is a man of war, and will not lodge with the people.

Behold, he is hid now in some pit, or in some other place: and it will come to pass, when some of them be overthrown at the first, that whosoever heareth it will say, There is a slaughter among the people that follow Absalom.

And he also that is valiant, whose heart is as the heart of a lion, shall utterly melt: for all Israel knoweth that thy father is a mighty man, and they which be with him are valiant men.

Therefore I counsel that all Israel be generally gathered unto thee, from Dan even to Beersheba, as the sand that is by the sea for multitude; and that thou go to battle in thine own person.
