'Expense' in the Bible

He shall take from the congregation of the Israelites [at their expense] two male goats as a sin offering and one ram as a burnt offering.

Then all the men of Judah answered the men of Israel, “Because the king is a close relative to us. So why then are you angry about this matter? Have we eaten at all at the king’s expense? Or has anything been taken for us?”

But the former governors who were [in office] before me put heavy burdens on the people and took food and wine from them in addition to forty shekels of silver [as an excessive monthly salary]; even their servants assumed authority over the people. But I did not do so because of the [reverent] fear of God.
