1 Kings 1:9-10 says "Adonijah then sacrificed sheep, cattle and fattened calves at the Stone of Zoheleth near En Rogel. He invited all his brothers, the king's sons, and all the men of Judah who were royal officials, (10) but he did not invite Nathan the prophet or Benaiah or the special guard or his brother Solomon."
It was obvious what Adonijah was up to; not by who he invited, but by who he did not invite. He only invited those whom he knew would tell him what he wanted to hear. He conveniently left Nathan the prophet, the special guard and his brother Solomon off the guest list.
We need to be very careful that we do not do the same thing by surrounding ourselves with people who we know will always tell us what we "want" to hear and not necessarily what we "need" to hear.
