III. He attributes this to their ignorance and inconsideration (v. 3): The ox knows, but Israel does not. Observe, 1. The sagacity of the ox and the ass, which are not only brute creatures, but of the dullest sort; yet the ox has such a sense of duty as to know his owner and to serve him, to submit to his yoke and to draw in it; the ass has such a sense of interest as to know has master's crib, or manger, where he is fed, and to abide by it; he will go to that of himself if he be turned loose. A fine pass man has come to when he is shamed even in knowledge and understanding by these silly animals, and is not only sent to school to them (Prov. vi. 6, 7), but set in a form below them (Jer. viii. 7), taught more than the beasts of the earth (Job xxxv. 11) and yet knowing less. 2. The sottishness and stupidity of Israel. God is their owner and proprietor. He made us, and his we are more than our cattle are ours; he has provided well for us; providence is our Master's crib; yet many that are called the people of God do not know and will not consider this, but ask, "What is the Almighty that we should serve him? He is not our owner; and what profit shall we have if we pray unto him? He has no crib for us to feed at." He had complained (v. 2) of the obstinacy of their wills; They have rebelled against me. Here he runs it up to its cause: "Therefore they have rebelled because they do not know, they do not consider." The understanding is darkened, and therefore the whole soul is alienated from the life of God, Eph. iv. 18. "Israel does not know, though their land is a land of light and knowledge; in Judah is God known, yet, because they do not live up to what they know, it is in effect as if they did not know. They know; but their knowledge does them no good, because they do not consider what they know; they do not apply it to their case, nor their minds to it." Note, (1.) Even among those that profess themselves God's people, that have the advantages and lie under the engagements of his people, there are many that are very careless in the affairs of their souls. (2.) Inconsideration of what we do know is as great an enemy to us in religion as ignorance of what we should know. (3.) Therefore men revolt from God, and rebel against him, because they do not know and consider their obligations to God in duty, gratitude, and interest.
