How can we accept the majority of Proverbs by Solomon when 1 Kings 11:6 says, “So Solomon did what was evil in the eyes of Jehovah and did not fully follow Jehovah, as David his father had done”?
The Proverbs
The Book of Proverbs (Hebrew: מִשְלֵי, Míshlê (Shlomoh), "Proverbs (of Solomon)") is a book in the third section (called Ketuvim) of the Hebrew Bible and a book of the Christian Old Testament. Proverbs raises questions of values, moral behavior, the meaning of human life, and righteous conduct.
Book of Ecclesiastes
"There is no doubt that the book contains a good deal of sobering truths about life, but they are mentioned to contrast with other truths that demonstrate what life can be like when God intervenes. This is not a life devoid of pain, suffering, and confusion over what God is doing (Wright, “The Riddle of the Sphinx,” 334). Indeed, Ecclesiastes is quite clear in stating that we can't fully know the mind of God (Whybray, Ecclesiastes, 29-30). Statements about the limitations of human understanding are common (see Eccl. 1:18; 3:11). The writer is prodding us to realize that no matter how exciting our life may be, it is ultimately meaningless apart from God." - David Moore; Dr. Daniel L. Akin
The Song of Solomon
"Although often called the Song of Solomon, the Hebrew title for the book is “Song of Songs.” This is how the Hebrew language says “The Best Song.” The book portrays the deep, genuine love between a man and a woman in marriage. The subject of the book is quite obviously sexual in nature. The intimacy and physical pleasure God intended for a man and a woman is tastefully and appealingly put on full display before us (cf. Gen. 2:15-25)." - David Moore; Dr. Daniel L. Akin
