'Tax gatherer' in the Bible

The Pharisee, standing by himself, made this prayer: God, I thank thee, that I am not as the rest of mankind, extortioners, unjust, adulterers, or as this tax-gatherer.

And the tax-gatherer standing at a distance, would not even so much as lift his eyes heaven-ward, but smote on his breast, saying, May God accept the atonement for me a sinner!
