'Willing' in the Bible

However, Saul and the army spared Agag and the best of the sheep and the cattle and the second [best] of the young fatlings and {all that was valuable}; they were not willing to utterly destroy them. But all the possessions that were despised or worthless, they utterly destroyed.

So the king said to the runners [who were] stationed around him, "Turn and kill the priests of Yahweh, because {they also support David} and because they knew that he was fleeing and {did not disclose it to me}." But the servants of the king [were] not willing to raise their hand to attack the priests of Yahweh.

Yahweh repays to each [one] his righteousness and his faithfulness, for Yahweh gave you into my hand today, but I was not willing to stretch out my hand against Yahweh's anointed.

Then Saul said to {his armor bearer}, "Draw your sword and thrust me through with it, so that these uncircumcised do not come and thrust me through and make a fool of me!" But {his armor bearer} [was] not willing [to do so] because he [was] very afraid. So Saul took the sword and fell on it.
