John Calvin's Bible Commentary
Jeremiah 23:35
Here the Prophet explains himself more clearly; he shews why God would not have his word to be called a burden. Why so? because they in a manner closed the way, so that they derived no benefit from God’s word, while they regarded it with disdain and hatred; for the word burden was an obstacle, so that they gave no access to God, nor opened their ears to hear his word. God then bids them to come with empty and sincere hearts; for it is a real preparation for a teachable spirit, when we acknowledge that we ought to believe in God’s word, and also when we are not possessed by a perverse feeling which forms a prejudice and in a manner holds us bound, so that we are not free to form a right judgment.
The import of the passage then is this, that the Jews, renouncing their blasphemies, were to prepare themselves reverently to hear God’s word, for hearing is due to God; and then that this word was to be heard with sincere hearts, so that no weariness, nor pride, nor hatred, nor any depraved feeling, might hinder his word from being believed and reverently heard by all. This then is what the Prophet means when he says, “Ye shall hereafter change your impious expression, and shall say, What has Jehovah answered? what has Jehovah spoken?” That is, they shall not themselves close the door, but willingly come to the school of God, being meek and teachable, so that nothing would hinder them from rendering honor to God and from embracing his word, that they might be terrified by his threatenings, and that being allured by his promises they might devote themselves wholly to him.
