'Need' in the Bible

Jacob said, “Look, the sun is still high [overhead]; it is a long time before the flocks need to be gathered [in their folds for the night]. Water the sheep, and go, and return them to their pasture.”

But Jacob replied, “You know, my lord, that the children are frail and need gentle care, and the nursing flocks and herds [with young] are of concern to me; for if the men should drive them hard for a single day, all the flocks will die.

Then Esau said, “Please let me leave with you some of the people who are with me.” But Jacob said, “What need is there [for it]? Let me find favor in the sight of my lord.”
