New Defender's Study Bible Notes
21:2 in his own eyes. Even imprisoned criminals are commonly found still to be justifying—or at least ignoring—the sinful deeds which caused their problems, and blaming others instead. The human “heart is deceitful above all things, and desperately wicked” (Jeremiah 17:9). It takes God Himself, the Holy Spirit, to bring true conviction and repentance to the heart of a sinner (John 16:7-11).
21:3 than sacrifice. Note also Micah 6:7-8; Psalm 51:16-17; Hosea 6:6; I Samuel 15:22; Matthew 9:13.
21:27 abomination. Pious adherence to rules of religious ritualism is hypocrisy without a godly life. It is here called “abomination,” a word often used to describe idolatry. Thus even religious practices ordained by God can become equivalent to idolatry under such circumstances. Note also Proverbs 28:9.
21:30 no wisdom. Those intellectuals who reject the Lord as Creator and Savior, despite their pretense of superior wisdom, are actually fools (Psalm 14:1). The very foundation of true wisdom and knowledge is “the fear of the LORD” (Proverbs 1:7; 9:10), and in Christ “are hid all the treasures of wisdom and knowledge” (Colossians 2:3).
