'Needs' in the Bible

For we must needs die, and are as water spilt on the ground, which cannot be gathered up again; neither doth God respect any person: yet doth he devise means, that his banished be not expelled from him.

Barzillai was a very old man—80 years old—and since he was a very wealthy man, he had provided for the needs of the king while he stayed in Mahanaim.

Then David went to his palace in Jerusalem. The king took the ten concubines he had left to care for the palace and placed them under confinement. Though he provided for their needs, he did not have sexual relations with them. They remained in confinement until the day they died, living out the rest of their lives as widows.
