1 sn “Honor” in this passage probably means respect, external recognition of worth, accolades, advancement to high position, etc. All of these would be out of place with a fool; so the sage is warning against elevating or acclaiming those who are worthless. See also J. A. Emerton, “Notes on Some Passages in the Book of Proverbs,” VT 15 (1965): 271-79.

3 sn The wisdom of the ants is found in their diligent preparation (כּוּן, kun) of food supplies in the summer for times in the winter when food is scarce. See S. P.
