2 Samuel 15:32

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.
