New Defender's Study Bible Notes
13:9 adultery. The law has not been abrogated by Christ, but fulfilled by Him and its curse removed (Matthew 5:17; Galatians 3:13; I Corinthians 15:56-57). All of God’s Ten Commandments are repeated, in effect, in the New Testament (see note on Hebrews 4:9 relative to the law of the sabbath, which is sometimes said to be an exception to this). Here the commands of the second table of the law are cited, having to do with our responsibilities to our fellow men.
13:9 this saying, namely. See Matthew 22:37-40, where Jesus applies the commands of Deuteronomy 6:5 and Leviticus 19:18 as summarizing the first and second tables of the law, respectively (the first table dealing with our responsibility to God). No one can be saved by keeping the law, but one who is saved by grace will love God’s law and diligently seek to obey it.
