Verse 13. - Will I eat the flesh of bulls, or drink the blood of goats? But is it to be supposed, can any suppose it possible, that I, the Lord of heaven and earth, the invisible Author of all things, both visible and invisible, can need material sustenance, and can condescend to find any sustenance in bulls' flesh and goats' blood? Scarcely did even the grossest of the heathen take this view. A vapour, an odour (κνίσση), was thought to ascend from the victims sacrificed, and this penetrated to the Olympian abodes, and gratified, or, as some would say, "fed" the gods. But such coarse feeding as that suggested in the text was hardly imagined by any, unless it were by utter savages and barbarians.

50:7-15 To obey is better than sacrifice, and to love God and our neighbour better than all burnt-offerings. We are here warned not to rest in these performances. And let us beware of resting in any form. God demands the heart, and how can human inventions please him, when repentance, faith, and holiness are neglected? In the day of distress we must apply to the Lord by fervent prayer. Our troubles, though we see them coming from God's hand, must drive us to him, not drive us from him. We must acknowledge him in all our ways, depend upon his wisdom, power, and goodness, and refer ourselves wholly to him, and so give him glory. Thus must we keep up communion with God; meeting him with prayers under trials, and with praises in deliverances. A believing supplicant shall not only be graciously answered as to his petition, and so have cause for praising God, but shall also have grace to praise him.Will I eat the flesh of bulls, or drink the blood of goats? That is, express a pleasure, take delight and satisfaction, in such kind of sacrifices, which can never take away sin: no, I will not; wherefore other sacrifices, more agreeable to his nature, mind, and will, and to the Gospel dispensation, are next mentioned.
