The New Testament frequently incorporates minor word variations when quoting Old Testament passages. Some Bible critics have pointed to these variations suggesting that the Bible contains contradictions. However, Bible-believing students know that these variations actually provide additional light and understanding of God’s word. For example, Romans 3:13 quotes Psalm 5:9 with the variation in wording shedding light on the meaning of the word flattery. The phrase from Psalms reads “they flatter with their tongue” (Psalm 5:9). Romans modifies this Old Testament quotation by stating that “with their tongues they have used deceit” (Romans 3:13). This indicates that flattery involves the use of deceitful words; and according to 1 Thessalonians 2:5, the motive is often connected to covetousness.
Man-made religions have always unwisely taught followers to establish their own righteousness. In the garden in Eden, Adam and Eve clothed themselves with fig leaves in an attempt to cover their nakedness caused by sin. Men built the tower of Babel hoping that this device could help them reach into heaven. The Bible describes man’s righteousness as “filthy rags” (Isaiah 64:6). Today's passage tells of a people who went about to establish their own righteousness by refusing to submit to God’s righteousness. Man-made religions all err in the same way. They think that some work or act of obedience can somehow establish a level of righteousness that will ultimately and eventually satisfy God. Yet, the Bible points out the repeated futility of failing to submit to the righteousness of God.
