'Wages' in the Bible

He who plants and he who waters are one [in importance and esteem, working toward the same purpose]; but each will receive his own reward according to his own labor.

And if I preach willingly, I receive my wages; but if against my will, a stewardship has nevertheless been entrusted to me.

What are my wages then? The very fact that the Good News which I preach will cost my hearers nothing, so that I cannot be charged with abuse of my privileges as a Christian preacher.
