Proverbs 28:25

He that is of a proud heart stirreth up strife: but he that putteth his trust in the LORD shall be made fat.

Proverbs 28:25 belongs to the collection of Solomonic proverbs found in chapters 25 through 29, gathered in Hezekiah's time about three hundred years after Solomon. The word rendered heart denotes a person's inward disposition or desire, showing the soul or mind as the seat of passions and emotions. It is translated heart, showing that the word can refer to the heart or inner disposition.

The verse contrasts a proud heart that stirs up strife with trust in the Lord that brings prosperity. The trusting person walks in duty and humility. Being made fat means to prosper and be provided for, as a promise of God's care and a reason to trust him rather than rely on human protection.

Being made fat also means to be made spiritually rich, as the trusting soul feeds on the things of God and grows full, while distrust produces leanness of soul. Those who grow rich may become conceited, despise the poor, and deceive themselves.
