2 Chronicles 20:1-12

After this the Moabites and Ammonites, and with them some of the Meunites, came against Jehoshaphat for battle. Some men came and told Jehoshaphat, “A great multitude is coming against you from Edom, from beyond the sea; and, behold, they are in Hazazon-tamar” (that is, Engedi). Then Jehoshaphat was afraid and set his face to seek the Lord, and proclaimed a fast throughout all Judah. And Judah assembled to seek help from the Lord; from all the cities of Judah they came to seek the Lord.

And Jehoshaphat stood in the assembly of Judah and Jerusalem, in the house of the Lord, before the new court, 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. 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? And they have lived in it and have built for you in it a sanctuary for your name, saying, ‘If disaster comes upon us, the sword, judgment, 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.’ 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— behold, they reward us by coming to drive us out of your possession, which you have given us to inherit. 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.” (ESV)

Romans 8:26-28

Likewise the Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words. And he who searches hearts knows what is the mind of the Spirit, because the Spirit intercedes for the saints according to the will of God. And we know that for those who love God all things work together for good, for those who are called according to his purpose. (ESV)

Matthew 6:5-13

“And when you pray, you must not be like the hypocrites. For they love to stand and pray in the synagogues and at the street corners, that they may be seen by others. Truly, I say to you, they have received their reward. But when you pray, go into your room and shut the door and pray to your Father who is in secret. And your Father who sees in secret will reward you.

“And when you pray, do not heap up empty phrases as the Gentiles do, for they think that they will be heard for their many words. Do not be like them, for your Father knows what you need before you ask him. Pray then like this:

“Our Father in heaven,
hallowed be your name.
Your kingdom come,
your will be done,
    on earth as it is in heaven.
Give us this day our daily bread,
and forgive us our debts,
    as we also have forgiven our debtors.
And lead us not into temptation,
    but deliver us from evil. (ESV)
