1: ὀφειλέτης
(Strong's #3781 — Noun Masculine — opheiletes — of-i-let'-ace )

"one who owes anything to another," primarily in regard to money; in Matthew 18:24 , "who owed" (lit., "one was brought, a debtor to him of ten thousand talents"). The slave could own property, and so become a "debtor" to his master, who might seize him for payment.

2: χρεωφειλέτης
(Strong's #5533 — Noun Masculine — chreopheiletes — khreh-o-fi-let'-ace )

lit., "a debt-ower" (chreos, "a loan, a debt," and No. 1), is found in Luke 7:41 , of the two "debtors" mentioned in the Lord's parable addressed to Simon the Pharisee, and in Luke 16:5 , of the "debtors" in the parable of the unrighteous steward. This parable indicates a system of credit in the matter of agriculture. In the Sept., Job 31:37 , "having taken nothing from the debtor;" Proverbs 29:13 , "when the creditor and the debtor meet together." The word is more expressive than No. 1.
