“Whoever is simple, let him turn in here!” To him who lacks sense she says,

Matthew Henry Presbyterian @wholebiblehenry

Wisdom is here introduced as a magnificent and munificent queen, very great and very generous; that Word of God is this Wisdom in which God makes known his goodwill towards men; God the Word is this Wisdom, to whom the Father has committed all judgment.

Commenting on Proverbs 9:1-12

John Gill Reformed Baptist @doctorgill

Whoso is simple, let him turn in hither,.... Into Wisdom's house, so well built and furnished; the church of Christ, as a house of instruction; a school, where such who are "simple", weak, and foolish, may learn. Here are many instructors; saints instruct one another; ministers of the word are teachers; yea, Father, Son, and Spirit, here teach and instruct, and none teach like them.

Jamieson-Fausset-Brown Reformed @jfbcommentary

(Compare Pro 1:4; Pro 6:32). Wisdom not only supplies right but forbids wrong principles.
