The translation posted by Atlas, is one of the reasons I left Islam.
I will translate it as I truly believe it ought to be now:
"Men regarding woman are to be lifters (moral supports), by what God has made some of them excel others in and by what the spend of their wealth, so the righteous woman are obedient, guarding the hidden by which God has guarded, and regarding those who you fear betrayal, advise them but do leave them alone regarding this in the beds and continue to have intercourse (beat is take an expression by me as to sex, Quran never mentions sex directly once) with them, therefore if they obey you (ie. your advice) do not seek a way against them, verily God is exalted, great."
There is another verse that explicitly says "do not treat them harshly" - let alone the question of beating them because you fear they are betraying you!
