▼tn The sentence uses the infinitive absolute and the imperfect from יָדַע (yadaʿ, “to know”). The imperfect here has been given the obligatory nuance, “you must know,” and that has to be intensified with the infinitive.

▼tn Heb “the faces of your flock.”

▼tn לֵב (lev) means “mind, heart” and by extension can refer to aspects of thinking or the will. The Hebrew idiom “set the mind (לֵב) on” or “put the mind (לֵב) to” transfers easily to English and is another way of saying to pay careful attention to something.

▼sn The care of the flock must become the main focus of the will, for it is the livelihood. So v. 23 forms the main instruction of this lengthy proverb (vv. 23-27).
