2 Samuel 16:2

The asses be for the king's household to ride on Or, rather, some of his household, for they could not all ride on two asses, unless by turns, relieving each other, which perhaps Ziba intended; for he seems to have been very considerate in adapting his present to the wants of David and those that were with him. It appears, the king, and his wives and children, were all on foot: not because he had not, or could not procure, asses for them at Jerusalem; but because he chose they should go in this manner, as best becoming that state of penitence and humiliation in which they were.
