John Trapp on Proverbs 4:20

Verſ. 20. My Son, attend to my words] Still hee calls for attention, as knowing our dulneſs, and ſickle headedneſs. It fated with the Prophet Zachary as with a drowſie perſon, who though awaked and ſet to work, is ready to ſleep at it, Zach. 4.1. It fares with many of us, as with little children, who though ſaying their Leſſons, yet muſt needs look off, to ſee the feather that flies by them.
