'Part' in the Bible

And if a man takes part in a competition he does not get the crown if he has not kept the rules.

But take no part in wrong and foolish talk, for those who do so will go farther into evil,

I for my part am like a drink-offering which is already being poured out; and the time for my departure is now close at hand.

At my first defence no one took my part, but all forsook me: may it not be laid to their account.
