Exegesis:

statheis lit. ‘having taken his stand,’ in Luke always used of a person who is about to make an important statement (v. 40; 19.8; Acts 2.14; 5.20; 17.22; 27.21), and meaning either that the person stood up from sitting, or that he took a position, or a place from which to speak. Here it may suggest that the Pharisee took a position where he could be seen by the public.

pros heauton tauta prosēucheto ‘prayed to himself this.’ pros heauton is here equivalent to en heautō ‘in himself,’ i.e. ‘silently.’

ho theos, eucharistō soi ‘O God, I thank you.’ ho theos is nominative with the force of a vocative.

hoti ouk eimi hōsper hoi loipoi tōn anthrōpōn ‘that I am not like the rest of men.’ hoi loipoi takes up tous loipous in v. 9.

harpax ‘robber,’ or ‘swindler,’ probably the latter.

adikoi lit. ‘unrighteous (people),’ here used as a substantive, ‘law breakers,’ ‘criminals.’

moichoi ‘adulterers.’

ē kai hōs houtos ho telōnēs ‘or, for that matter, like that tax collector.’ kai means that the tax-collector is in the same class as the other people named.

Translation:

Prayed … with himself, or “silently prayed” (The Four Gospels – a New Translation), ‘prayed in his heart/mind,’ ‘prayed, thus his-unuttered-thought’ (Javanese).

I thank thee, see on 2.38.

Extortioners, unjust, adulterers. The appositional construction has equational force; it implies that the Pharisee declares all people other than himself and his group to be extortioners etc. It is sometimes better to shift to a relative clause, e.g. .’.. the rest of men, who are extortioners….’ — Extortioners, or, ‘robbers’ (cf. on 10.30), preferably ‘swindlers,’ i.e. persons who take other people’s property away by fraud or deceit.

Or even like …, preferably, ‘or also like…,’ ‘or again like…’ (Bible de Jérusalem) (see Exegesis). The phrase is dependent on ‘that I am not,’ or, ‘I thank you … that I am not,’ which may better be repeated, cf. Good News Translation.
