Wisdom is the Principal Thing

“You will not certainly die,” the serpent said to the woman. “For God knows that when you eat from it your eyes will be opened, and you will be like God, knowing good and evil.”

When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable for gaining wisdom, she took some and ate it. She also gave some to her husband, who was with her, and he ate it. Then the eyes of both of them were opened...

To the woman [God] said,
“I will make your pains in childbearing very severe;
with painful labor you will give birth to children.
Your desire will be for your husband,
and he will rule over you.”

To Adam he said, “Because you listened to your wife and ate fruit from the tree about which I commanded you, ‘You must not eat from it,’
“Cursed is the ground because of you;
through painful toil you will eat food from it
all the days of your life.
It will produce thorns and thistles for you,
and you will eat the plants of the field.
By the sweat of your brow
you will eat your food
until you return to the ground,
since from it you were taken;
for dust you are
and to dust you will return.”

Genesis 3:4-7, 16-19

...the Lord appeared to Solomon during the night in a dream, and God said, “Ask for whatever you want me to give you.”

Solomon answered, “...You have made your servant king in place of my father David. But I am only a little child and do not know how to carry out my duties.... So give your servant a discerning heart to govern your people and to distinguish between right and wrong. For who is able to govern this great people of yours?”

The Lord was pleased that Solomon had asked for this. So God said to him, “Since you have asked for this and not for long life or wealth for yourself, nor have asked for the death of your enemies but for discernment in administering justice, I will do what you have asked. I will give you a wise and discerning heart, so that there will never have been anyone like you, nor will there ever be. Moreover, I will give you what you have not asked for—both wealth and honor—so that in your lifetime you will have no equal among kings."

I Kings 3:5-13

Wisdom is the most important thing; so get wisdom.
If it costs everything you have, get understanding.
