'Expense' in the Bible

Then King Solomon swore by Yahweh, saying, "Thus may God do to me and thus may he add, if Adonijah hasn't spoken this thing at the expense of his life.

So go gather all of Israel to meet me on Mount Carmel. Bring along 450 prophets of Baal and 400 prophets of the Asherah who are funded at Jezebel's expense."
