'Need' in the Bible

She and her daughters-in-law prepared to leave the land of Moab, because she had heard in Moab that the Lord had paid attention to His people’s need by providing them food.

So Boaz said to Ruth, "Listen carefully, my dear! Do not leave to gather grain in another field. You need not go beyond the limits of this field. You may go along beside my female workers.

Keep your eyes on the field they are cutting, and go after them; have I not given orders to the young men not to put a hand on you? And when you are in need of drink go to the vessels and take of what the young men have put there.
