1. His own example (v. 19): O Lord! to thee will I cry. He would not put them upon doing that which he would not resolve to do himself; nay, whether they would do it or no, he would. Note, If God's ministers cannot prevail to affect others with the discoveries of divine wrath, yet they ought to be themselves affected with them; if they cannot bring others to cry to God, yet they themselves be much in prayer. In time of trouble we must not only pray, but cry, must be fervent and importunate in prayer; and to God, from whom both the destruction is and the salvation must be, ought our cry to be always directed. That which engaged him to cry to God was, not so much any personal affliction, as the national calamity: The fire has devoured the pastures of the wilderness, which seems to be meant of some parching scorching heat of the sun, which was as fire to the fruits of the earth; it consumed them all. Note, When God calls to contend by fire it concerns those that have any interest in heaven to cry mightily to him for relief. See Num. xi. 2; Amos vii. 4, 5.
