Luke 18: 9 - 14
9 He also told this parable to some who trusted in themselves that they were righteous and despised others:
10 "Two men went up into the temple to pray, one a Pharisee and the other a tax collector.
11 The Pharisee stood and prayed thus with himself, `God, I thank thee that I am not like other men, extortioners, unjust, adulterers, or even like this tax collector.
12 I fast twice a week, I give tithes of all that I get.'
13 But the tax collector, standing far off, would not even lift up his eyes to heaven, but beat his breast, saying, `God, be merciful to me a sinner!'
14 I tell you, this man went down to his house justified rather than the other; for every one who exalts himself will be humbled, but he who humbles himself will be exalted."
