I thought it would be helpful to put down David Benner's description of the different core tendencies.  I appreciate the way he describes them in contrast to the Enneagram site.  The following is our of his book The Gift of Being Yourself.

Ones need to be perfect and, discovering that neither they nor anything else in their world is perfect, are tempted by self-righteous anger.  A good biblical example of this type is Paul.

Twos need to be loved and needed, and their competence in making this happen sets them up for pride.  Martha is a good biblical example of a Two.

Threes need to be successful and are tempted to deceit, as they do whatever they have to do to avoid failure and appear in the best possible light.  Jacob illustrates this type.

Fours need to be special and are tempted toward envy, escapist fantasy and a compromise of authenticity.  Joseph, the Old Testament patriarch, illustrates this type.

Fives need knowledge, long for fulfillment, and are tempted by greed, stinginess and critical detachment.  Thomas, the so-called doubting disciple fits this pattern.

Sixes need security and are tempted by fear, self-doubt and cowardice.  Timothy is a good example of a Six.

Sevens need to avoid pain and are tempted by gluttony and intemperance.  Solomon is a biblical example of this type.

Eights need power, self-relieance and opportunities to be against something and are tempted by lust, arrogance and the desire to possess and control others.  King Saul is a good illustration of an Eight.

Nines need to maintain emotional peace and avoid initiative and are tempted by laziness, comfortable illusions and being overly accomodating.  Jonah illustrates this type.
