Matthew Henry's Complete Bible Commentary

Verse 24

Note, 1. He is to be reckoned an intelligent man that not only has wisdom, but has it ready when he has occasion for it. He lays his wisdom before him, as his card and compass which he steers by, has his eye always upon it, as he that writes has on his copy; and then he has it before him; it is not to seek, but still at hand. 2. He that has a giddy head, a roving rambling fancy, will never be fit for any solid business. He is a fool, and good for nothing, whose eyes are in the ends of the earth, here, and there and every where, any where but where they should be, who cannot fix his thoughts to one subject nor pursue any one purpose with any thing of steadiness. When his mind should be applied to his study and business it is filled with a thousand things foreign and impertinent. MHBCC 646.24
