'Debt' in the Bible

Now a certain woman, the wife of one of the sons of the prophets, came crying to Elisha and said, Your servant my husband is dead; and to your knowledge he was a worshipper of the Lord; but now, the creditor has come to take my two children as servants in payment of his debt.

Then she came and told the man of God. And he said, Go, sell the oil, and pay thy debt, and live thou and thy children of the rest.
