Ezra 7:10

For Ezra had prepared his heart, &c. He had set his mind and affections upon it, and made it his chief business. To seek the law of the Lord To search and find out the true sense and meaning of it, and thence to learn what sins or errors were to be reformed, and what duties were to be performed. And to do it, and to teach in Israel The order of things in this verse is very observable: first, he endeavours to understand God's law and word, and that not for curiosity or ostentation, but in order to practice; next, he conscientiously practises what he did understand, which made his doctrine much more effectual; and then he earnestly desires and labours to instruct others, that they also might know and do it.
