Concise Bible Dictionary:

The word is ἄνομος, and is translated “without law” in 1 Corinthians 9:2121To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law. (1 Corinthians 9:21); it is applied to those who, regardless of all law, do their own will (Acts 2:2323Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain: (Acts 2:23) Thess. 2:8; 1 Tim. 1:99Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, (1 Timothy 1:9); 2 Pet. 2:88(For that righteous man dwelling among them, in seeing and hearing, vexed his righteous soul from day to day with their unlawful deeds;) (2 Peter 2:8)). It is wrongly translated “transgressor” in the AV of Mark 15:2828And the scripture was fulfilled, which saith, And he was numbered with the transgressors. (Mark 15:28) and Luke 22:3737For I say unto you, that this that is written must yet be accomplished in me, And he was reckoned among the transgressors: for the things concerning me have an end. (Luke 22:37). A kindred word is translated “transgression of the law” in 1 John 3:44Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law. (1 John 3:4), which as a definition of sin is a serious error: it should be “sin is lawlessness,” and this term is equally applicable to those who never had the law.
