Therein for thy name - "For the name of thy Word." - Targum.

And they dwelt therein,.... From ages past, hitherto, since it was first given them, and they were put into the possession of it:

and have built thee a sanctuary therein for thy name; a temple for his worship, honour, and glory, and for him to dwell in; and is a reason why it might be hoped he would protect them, especially when they prayed to him:

saying; and he promised to hear and help them, as follows.

In this land they dwelt, and built Thee therein a sanctuary for Thy name; cf. 2 Chronicles 6:5, 2 Chronicles 6:8. לאמר, saying, i.e., at the consecration of this house, having expressed the confident hope contained in the following words (2 Chronicles 20:9). In this verse, the cases enumerated in Solomon's dedicatory prayer, in which supplication is made that God would hear in the temple, are briefly summed up. By referring to that prayer, Jehoshaphat presupposes that Jahve had promised that He would answer prayer offered there, since He had filled the temple with His glory; see 2 Chronicles 7:1-3. The name שׁפות, which occurs only here, between דּבר and חרב, denotes in this connection a punitive judgment.

And they dwelt therein, and have built thee a sanctuary therein for thy name, saying,

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.
