'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.

So she came to the man of God and gave him word of what she had done. And he said, Go and get money for the oil and make payment of your debt, and let the rest be for the needs of yourself and your sons.
