David had prayed that God would open his eyes (Psa 119:18) and open the law (Psa 119:19); now here he pleads the earnestness of his desire for knowledge and grace, for it is the fervent prayer that avails much. 1. His desire was importunate: My soul breaketh for the longing it hath to thy judgments, or (as some read it) "It is taken up, and wholly employed, in longing for thy judgments; the whole stream of its desires runs in this channel. I shall think myself quite broken and undone if I want the word of God, the direction, converse, and comfort of it." 2. It was constant - at all times. It was not now and then, in a good humour, that he was so fond of the word of God; but it is the habitual temper of every sanctified soul to hunger after the word of God as its necessary food, which there is no living without.
