Matthew Henry Commentary Jeremiah 9:23-26

"Thus saith Jehovah, Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, let not the rich man glory in his riches; but let him that glorieth glory in this, that he hath understanding, and knoweth me, that I am Jehovah who exerciseth lovingkindness, justice, and righteousness, in the earth: for in these things I delight, saith Jehovah. Behold, the days come, saith Jehovah, that I will punish all them that are circumcised in [their] uncircumcision: Egypt, and Judah, and Edom, and the children of Ammon, and Moab, and all that have the corners [of their hair] cut off, that dwell in the wilderness; for all the nations are uncircumcised, and all the house of Israel are uncircumcised in heart." — Jeremiah 9:23-26 (ASV)

In this world of sin and sorrow, ending soon in death and judgment, how foolish it is for people to glory in their knowledge, health, strength, riches, or in anything that leaves them under the dominion of sin and the wrath of God! For these things, an account must be given in the future, and glorying in them will only increase their misery.

Those are the true Israel who worship God in the Spirit, rejoice in Christ Jesus, and have no confidence in the flesh.

Let us prize the distinction that comes from God and will last forever. Let us seek it diligently.
