1 Samuel 7:5-6

5Then Samuel said, “Gather all Israel at aMizpah, and I will pray to the Lord for you.” 6So they gathered at bMizpah cand drew water and poured it out before the Lord dand fasted on that day and said there, e“We have sinned against the Lord.” And Samuel judged the people of Israel at Mizpah.

2 Chronicles 20:3-13

3Then Jehoshaphat was afraid and set his face fto seek the Lord, and gproclaimed a fast throughout all Judah. 4And Judah assembled to seek help from the Lord; from all the cities of Judah they came to seek the Lord.

5And Jehoshaphat stood in the assembly of Judah and Jerusalem, in the house of the Lord, before the new court, 6and said, “O Lord, God of our fathers, are you not hGod in heaven? You irule over all the kingdoms of the nations. jIn your hand are power and might, so that none is able to withstand you. 7Did you not, our God, kdrive out the inhabitants of this land before your people Israel, and give it forever to the descendants of lAbraham your friend? 8And they have lived in it and have built for you in it a sanctuary for your name, saying, 9 mIf disaster comes upon us, the sword, judgment,
Or  the sword of judgment
or pestilence, or famine, owe will stand before this house and before you— pfor your name is in this house—and cry out to you in our affliction, and you will hear and save.’
10And now behold, the men of qAmmon and Moab and rMount Seir, whom syou would not let Israel invade when they came from the land of Egypt, tand whom they avoided and did not destroy 11behold, they reward us uby coming to drive us out of your possession, which you have given us to inherit. 12O our God, will you not vexecute judgment on them? For we are powerless against this great horde that is coming against us. We do not know what to do, but wour eyes are on you.”

13Meanwhile all Judah stood before the Lord, with their little ones, their wives, and their children.

even nursing infants.
abLet the bridegroom leave his room,
and the bride her chamber.
