(3) And Jehoshaphat.--And he was afraid (scil., at the news). And Jehoshaphat set his face, &c. Literally, put his face--a phrase used in Daniel 9:3 (comp. 2Kings 12:18), and implying resolved, determined.

To seek the Lord.--The Hebrew construction is that of 2Chronicles 15:13 (le is here a sign of the accusative).

Proclaimed a fast.--An act of national self-humiliation, implying an admission of guilt, and intended to evoke the Divine pity and succour. (Comp. Judges 20:26; Joel 2:12-17; 1Samuel 7:6; Ezra 8:21.)

Verse 3. - Proclaimed a fast. This is the first recorded occasion of a general fast by royal proclamation, and of individual fasting it is remarkable that there is no record before the time and the act of Moses (as e.g. Exodus 34:28); after which, for individual fasting, come occasions like those of David (2 Samuel 12:16) and Elijah (1 Kings 19:8); for general fasting, occasions like those of Joshua 7:6; Judges 20:26; 1 Samuel 7:6; and for partial fasting, by semi-royal authority, that "proclaimed" by Jezebel (1 Kings 21:9, 12).

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.And Jehoshaphat feared,.... Exceedingly, as the Targum adds, not merely because of the number of his enemies, for he had forces enough to go forth against them, see 2 Chronicles 17:14, but chiefly because the Lord had told him that wrath was upon him from him, 2 Chronicles 19:2 and he might fear that this was the time for the execution of it:

and set himself to seek the Lord; by prayer and supplication, with all seriousness, fervour, and constancy:

and proclaimed a fast throughout all Judah; a day of humiliation and mourning for sin before the Lord; when they were ordered to abstain from bodily food and labour, that they might be fit and more at leisure for spiritual exercises.
