Proverbs 4:7
“Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding.”
Get wisdom, get understanding: forget it not; neither decline from the words of my mouth.
Forsake her not, and she shall preserve thee: love her, and she shall keep thee.
Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding.
Exalt her, and she shall promote thee: she shall bring thee to honour, when thou dost embrace her.
She shall give to thine head an ornament of grace: a crown of glory shall she deliver to thee.
