"and you will eat and be sated": It is a good sign for a man when his beast eats and is stated, viz. (Proverbs 12:10) "The righteous one knows the spirit of his beast."
When your beast eats and is sated, it works the ground with vigor, viz. (Ibid. 14:4) "There is much produce in the power of the ox."
Variantly: "and you will eat and be sated": from the offspring. And even though there is no proof for this, it is intimated in (Jeremiah 31:12) "And they shall come and sing in the height of Zion, and they shall stream together to the goodness of the L-rd, for corn, and for wine, and for oil, and for the young of the flock and of the herd."
