Psalm of humility and trust.

v1: Contrast Acts 17.21; 1 Tim 1.7; see 1 Sam 17.28; we are to cherish the simple, pure truths of Scripture.

Avoid things that are too profound; beware the pursuit of knowledge for its own sake, for knowledge puffs up. Bible truths are essentially practical. But we should beware of seeking more knowledge merely for the sake of speculation.

v2: Simple trust in God, the essential mark of true godliness. Like a young child, weaned, happy, satisfied with its mother.

v3: Israel can therefore hope in the Lord always.
