Albert Barnes Commentary Psalms 34:10

"The young lions do lack, and suffer hunger; But they that seek Jehovah shall not want any good thing." — Psalms 34:10 (ASV)

The young lions do lack and suffer hunger—that is, they often do, as compared with the friends of God. The allusion is especially to the “young” lions who are not able to go out themselves in search of food.

Perhaps the idea is that they are dependent on the older lions—their parents—for the supply of their needs, just as the pious are dependent on God. However, the result shows that the lions’ reliance is often vain, while that of the pious never is. The old lions may be unable to procure food for their young; God is never unable to provide for the needs of His children.

If their needs are in any case unsupplied, it is for some other reason than because God is unable to meet their necessities. The word “lack” here—רושׁ rûsh—means to be poor; to suffer want; to be needy (Proverbs 14:20; Proverbs 18:23).

But they that seek the Lord—that seek Him as their Friend; that seek His favor; that seek what they need from Him. “To seek God” is a phrase which is often used to denote true piety. It means that we wish to know Him, that we desire His friendship, and that we seek all our blessings from Him.

Shall not want any good thing—any real good. God is able to supply every need. If anything is withheld, it is always certain that this is not because God could not confer it, but because He sees good reasons why it should not be conferred.

The real good—what we need most, what will most benefit us—will be bestowed on us. Universally, it may be said of all the children of God that everything in this world and the next that is really for their good will be granted.

They themselves are often not the best judges of what will be for their good, but God is an infallible Judge in this matter, and He will certainly bestow what is best for them.
