And Samuel told him every whit, and hid nothing from him. And he said, It is the LORD: let him do what seemeth him good. Samuel told him every whit - Our word whit, or wid, comes from the Anglo-Saxon, which signifies person, thing, etc.; every whit is every thing. The Hebrew את כל הדברים et col haddebarim, "all these words."
It is the Lord - He is Sovereign, and will do what he pleases; he is righteous, and will do nothing but what is just.
Let him do what seemeth him good - There is much of a godly submission, as well as a deep sense of his own unworthiness, found in these words. He also had sinned, so as to be punished with temporal death; but surely there is no evidence that the displeasure of the Lord against him was extended to a future state.
