Albert Barnes Commentary Jeremiah 10:12

"He hath made the earth by his power, he hath established the world by his wisdom, and by his understanding hath he stretched out the heavens:" — Jeremiah 10:12 (ASV)

Discretion - Or, understanding. The three attributes ascribed to the Creator are very remarkable. The creation of the earth, the material world, is an act of “power;” the “establishing,” i.e., the ordering and arranging it as a place fit for human habitation, is the work of his “wisdom;” while the spreading out the heavens over it like a tent is an act of “understanding,” or skill. Naturally, the consideration of these attributes has led many to see here an allusion to the Holy Trinity.
