[23:5] 1 tc The Kethib is הֲתָעוּף (hata’uf), “do your eyes fly [light] on it?” The Qere is the Hiphil, הֲתָעִיף (hata’if) “do you cause your eyes to fly on it?” But the line is difficult. The question may be indirect: If you cast your eyes on it, it is gone – when you think you are close, it slips away.
[23:5] 2 sn This seventh saying warns people not to expend all their energy trying to get rich because riches are fleeting (cf. Instruction of Amememope, chap. 7, 9:10-11 which says, “they have made themselves wings like geese and have flown away to heaven”). In the ancient world the symbol of birds flying away signified fleeting wealth.
