John Gill's Bible Commentary Ver. 2. And I will come upon him while he [is] weary , etc.] With travelling, and with grief, and when endeavouring to get some rest by sleep, and so surprise him unawares, when not on his guard, and in no posture of defence: and weak handed ; while the number of men with him is small, and before the people from different parts can come to his assistance: and will make him afraid ; strike terror into him and his then, by surprising them suddenly in the night with such a number of men: and all the people that [are] with him shall flee ; one one way, and another another, for their own security, and leave David alone: and I will smite the king only ; dispatch him, and let the people flee without pursuing them.
Matthew Henry Commentary
Verses 1-21 - Here was a wonderful effect of Divine Providence blinding Absalom' mind and influencing his heart, that he could not rest in Ahithophel' counsel, and that he should desire Hushai's advice. But there is n contending with that God who can arm a man against himself, and destro him by his own mistakes and passions. Ahithophel's former counsel wa followed, for God intended to correct David; but his latter counsel wa not followed, for God meant not to destroy him. He can overrule all counsels. Whatever wisdom or help any man employs or affords, the success is from God alone, who will not let his people perish.
