She perceiveth that her merchandise is good— She perceiveth that her merchandize is advantageous. Houbigant. The LXX read, She finds that it is good to work. "Finding by sweet experience not only how wholesome labour is, but what profit her traffic yields, she doth not conclude her work with the day, but continues it as much in the night as can be spared from necessary sleep." See the next verse. Very similar to this is what Penelope says to Ulysses:
Nec mihi quaerenti spatiosam fallere noctem, Lassaret viduas pendula tela manus.
Nor, seeking to deceive the tedious night, Would the worn distaff tire thy widow'd hands.
"See Ovid's Epistle of Penelope to Ulysses, and Pope's Odyss. book i. ver. 455.
