3 Then Jehoshaphat was afraid and set his face to seek the Lord, and proclaimed a fast throughout all Judah. 4 And Judah assembled to seek help from the Lord; from all the cities of Judah they came to seek the Lord. 5 And Jehoshaphat stood in the assembly of Judah and Jerusalem, in the house of the Lord, before the new court, 6 and said, "O Lord, God of our fathers, are you not God in heaven? You rule over all the kingdoms of the nations. In your hand are power and might, so that none is able to withstand you. 7 Did you not, our God, drive out the inhabitants of this land before your people Israel, and give it forever to the descendants of Abraham your friend? 8 And they have lived in it and have built for you in it a sanctuary for your name, saying, 9 'If disaster comes upon us, the sword, judgment,[1] or pestilence, or famine, we will stand before this house and before you-- for your name is in this house--and cry out to you in our affliction, and you will hear and save.' 10 And now behold, the men of Ammon and Moab and Mount Seir, whom you would not let Israel invade when they came from the land of Egypt, and whom they avoided and did not destroy-- 11 behold, they reward us by coming to drive us out of your possession, which you have given us to inherit. 12 O our God, will you not execute judgment on them? For we are powerless against this great horde that is coming against us. We do not know what to do, but our eyes are on you." 13 Meanwhile all Judah stood before the Lord, with their little ones, their wives, and their children.

Commentary on 2 Chronicles 20:1-13

(Read 2 Chronicles 20:1-13)

In all dangers, public or personal, our first business should be to seek help from God. Hence the advantage of days for national fasting and prayer. From the first to the last of our seeking the Lord, we must approach him with humiliation for our sins, trusting only in his mercy and power. Jehoshaphat acknowledges the sovereign dominion of the Divine Providence. Lord, exert it on our behalf. Whom should we seek to, whom should we trust to for relief, but the God we have chosen and served. Those that use what they have for God, may comfortably hope he will secure it to them. Every true believer is a son of Abraham, a friend of God; with such the everlasting covenant is established, to such every promise belongs. We are assured of God's love, by his dwelling in human nature in the person of the Saviour. Jehoshaphat mentions the temple, as a token of God's favourable presence. He pleads the injustice of his enemies. We may well appeal to God against those that render us evil for good. Though he had a great army, he said, We have no might without thee; we rely upon thee.
