יָדֹ֣עַ תֵּ֭דַע פְּנֵ֣י צֹאנֶ֑ךָ שִׁ֥ית לִ֝בְּךָ֗ לַעֲדָרִֽים׃
Be thou diligent to know the state of thy flocks, And look well to thy herds;
Rashi on Proverbs
the condition of your flocks lit. the face of your flocks. Do not think lightly of always paying attention to them to determine what they require.
