Proverbs 20:13-15

¹³ 
Do not love [excessive] sleep, or you will become poor;
Open your eyes [so that you can do your work] and you will be satisfied with bread.
¹⁴ 
“It is [almost] worthless, it is [almost] worthless,” says the buyer [as he negotiates the price];
But when he goes his way, then he boasts [about his bargain].

There is gold, and an abundance of pearls,
But the lips of knowledge are a vessel of preciousness [the most precious of all].^(A)
