'Desires' in the Bible

If the man said to him, "Let the fat be burned first, and then take as much as your soul desires;" then he would say, "No, but you shall give it to me now; and if not, I will take it by force."

Saul said, "You shall tell David, 'The king desires no dowry except one hundred foreskins of the Philistines, to be avenged of the king's enemies.'" Now Saul thought to make David fall by the hand of the Philistines.

Then Jonathan said to David, "Whatever your soul desires, I will even do it for you."
