'Expense' in the Bible

because he loves our nation and he built us our synagogue [at his own expense].”

And Paul lived there for two full years [at his own expense] in his own rented lodging and welcomed all who came to him,

do not boast over the [broken] branches and exalt yourself at their expense. If you do boast and feel superior, remember that it is not you who supports the root, but the root that supports you.

Have we not the right to our food and drink [at the expense of the churches]?

[Consider this:] Who at any time serves as a soldier at his own expense? Who plants a vineyard and does not eat its fruit? Or who tends a flock and does not use the milk of the flock?

What then is my reward? [Just this:] that, when I preach the gospel, I may offer the gospel without charge [to everyone], so as not to take advantage of my rights [as a preacher and apostle] in [preaching] the gospel.

Or did I [perhaps] sin by humbling myself so that you might be exalted and honored, because I preached God’s gospel to you free of charge?
