'Willing' in the Bible

Saul and the troops spared Agag, and the best of the sheep, cattle, and choice animals, as well as the young rams and the best of everything else. They were not willing to destroy them, but they did destroy all the worthless and unwanted things.

And the king saith to runners, those standing by him, 'Turn round, and put to death the priests of Jehovah, because their hand also is with David, and because they have known that he is fleeing, and have not uncovered mine ear;' and the servants of the king have not been willing to put forth their hand to come against the priests of Jehovah.

May the Lord repay every man for his righteousness and his loyalty. I wasn’t willing to lift my hand against the Lord’s anointed, even though the Lord handed you over to me today.

and Saul saith to the bearer of his weapons, 'Draw thy sword, and pierce me with it, lest they come -- these uncircumcised -- and have pierced me, and rolled themselves on me;' and the bearer of his weapons hath not been willing, for he is greatly afraid, and Saul taketh the sword, and falleth upon it.
