13 The Master said: "These people make a big show of saying the right thing, but their hearts aren't in it. Because they act like they're worshiping me but don't mean it, 14 I'm going to step in and shock them awake, astonish them, stand them on their ears. The wise ones who had it all figured out will be exposed as fools. The smart people who thought they knew everything will turn out to know nothing."

Matthew Henry's Commentary on Isaiah 29:13-14

Commentary on Isaiah 29:9-16

(Read Isaiah 29:9-16)

The security of sinners in sinful ways, is cause for lamentation and wonder. The learned men, through prejudice, said that the Divine prophecies were obscure; and the poor urged their want of learning. The Bible is a sealed book to every man, learned or unlearned, till he begins to study it with a simple heart and a teachable spirit, that he may thence learn the truth and the will of God. To worship God, is to approach him. And if the heart be full of his love and fear, out of the abundance of it the mouth will speak; but there are many whose religion is lip-labour only. When they pretend to be speaking to God, they are thinking of a thousand foolish things. They worship the God of Israel according to their own devices. Numbers are only formal in worship. And their religion is only to comply with custom, and to serve their own interest. But the wanderings of mind, and defects in devotion, which are the believer's burden, are very different from the withdrawing of the heart from God, so severely blamed. And those who make religion no more than a pretence, to serve a turn, deceive themselves. And as those that quarrel with God, so those that think to conceal themselves from him, in effect charge him with folly. But all their perverse conduct shall be entirely done away.
