Proverbs 1

At the end of the period of Judges, we read -

"In those days there was no king in Israel: every man did that which was right in his own eyes." (Old Testament | Judges 21:25)

With that, Isaiah warned -

"Woe unto them that are wise in their own eyes, and prudent in their own sight!" (Old Testament | Isaiah 5:21)

Jacob also taught -

"...O the vainness, and the frailties, and the foolishness of men! When they are learned they think they are wise, and they hearken not unto the counsel of God, for they set it aside, supposing they know of themselves, wherefore, their wisdom is foolishness and it profiteth them not. And they shall perish.
29 But to be learned is good if they hearken unto the counsels of God." (Book of Mormon | 2 Nephi 9:28 - 29)

In Solomon's great wisdom, he said -

"The fear of the LORD is the beginning of knowledge: but fools despise wisdom and instruction." (Old Testament | Proverbs 1:7)

Solomon explained what is wisdom -

"A wise man will hear, and will increase learning; and a man of understanding shall attain unto wise counsels:" (Old Testament | Proverbs 1:5)

Why is it wise to follow the Lord? The Lord said to Abraham -

"...These two facts do exist, that there are two spirits, one being more intelligent than the other; there shall be another more intelligent than they; I am the Lord thy God, I am more intelligent than they all." (Pearl of Great Price | Abraham 3:19)

Because of that -
"...the LORD giveth wisdom: out of his mouth cometh knowledge and understanding." (Old Testament | Proverbs 2:6)

Thus we are told -

"Trust in the LORD with all thine heart; and lean not unto thine own understanding.
6 In all thy ways acknowledge him, and he shall direct thy paths." (Old Testament | Proverbs 3:5 - 6)

Therefore -

"Be not wise in thine own eyes: fear the LORD, and depart from evil." (Old Testament | Proverbs 3:7)
