And it came to pass, that [when] David was come to the top [of
 the mount]
 Of the mount of Olives: 
 where he worshipped God;
 by prayer and praise; here very probably he composed and sung the third psalm ( Psalms 3:1-8 ) , which, as the title shows, was made when he fled from Absalom: 
 behold, Hushai the Archite came to meet him, with his coat rent, and
 earth upon his head;
 in token of mourning, and as a bringer of bad tidings, see ( 2 Samuel 1:2 ) ; perhaps he was an inhabitant of Archi, at least originally, which lay on the borders of the tribe of Ephraim, ( Joshua 16:2 ) ; from whence he had his name.
