Verse 20. "Thou shalt eat it-in the place which the Lord shall choose" - Thus God in his mercy made their duty and interest go hand in hand. And in every case God acts thus with his creatures; well, therefore, might Satan ask, Doth Job serve God for naught? No! nor does God design that any man should.
Verse 21. "If there be any blemish" - See the notes on "Leviticus xxii. 20".
God will have both a perfect priest and a perfect offering.
