See on Luke 12:3.

A word formed in imitation of the sound, battalogein: properly, to stammer; then to babble or prate, to repeat the same formula many times, as the worshippers of Baal and of Diana of Ephesus (1 Kings 18:26; Acts 19:34) and the Romanists with their paternosters and aves.

So, rightly, A. V., and Rev. (compare Luke 11:4). Sin is pictured as a debt, and the sinner as a debtor (compare Matthew 18:28, Matthew 18:30). Accordingly the word represents sin both as a wrong and as requiring satisfaction. In contrast with the prayer, "Forgive us our debts," Tholuck ("Sermon on the Mount") quotes the prayer of Apollonius of Tyana, "O ye gods, give me the things which are owing to me."

Forgive (ἀφήκαμεν)

Lit., to send away, or dismiss. The Rev. rightly gives the force of the past tense, we have forgiven; since Christ assumes that he who prays for the remission of his own debts has already forgiven those indebted to him.

It is a mistake to define this word as only solicitation to evil. It means trial of any kind, without reference to its moral quality. Thus, Genesis 22:1 (Sept.), "God did tempt Abraham;" "This he said to prove him" (John 6:6); Paul and Timothy assayed to go to Bithynia (Acts 16:7); "Examine yourselves" (2 Corinthians 13:5). Here, generally of all situations and circumstances which furnish an occasion for sin. We cannot pray God not to tempt us to sin, "for God cannot be tempted with evil, neither tempteth he any man" (James 1:13).

The Lord here uses another word for sins, and still another (ἁμαρτιας) appears in Luke's version of the prayer, though he also says, "every one that is indebted to us." There is no difficulty in supposing that Christ, contemplating sins in general, should represent them by different terms expressive of different aspects of wrong-doing (see on Matthew 1:21). This word is derived from παραπίπτω, to fall or throw one's self beside. Thus it has a sense somewhat akin to ἁμαρτία, of going beside a mark, missing. In classical Greek the verb is often used of intentional falling, as of throwing one's self upon an enemy; and this is the prevailing sense in biblical Greek, indicating reckless and wilful sin (see 1 Chronicles 5:25; 1 Chronicles 10:13; 2 Chronicles 26:18; 2 Chronicles 29:6, 2 Chronicles 29:19; Ezekiel 14:13; Ezekiel 18:26). It does not, therefore, imply palliation or excuse. It is a conscious violation of right, involving guilt, and occurs therefore, in connection with the mention of forgiveness (Romans 4:25; Romans 5:16; Colossians 2:13; Ephesians 2:1, Ephesians 2:5). Unlike παράβασις (transgression), which contemplates merely the objective violation of law, it carries the thought of sin as affecting the sinner, and hence is found associated with expressions which indicate the consequences and the remedy of sin (Romans 4:25; Romans 5:15, Romans 5:17; Ephesians 2:1).
