In all conflicts we must look up to heaven for strength and it is believing prayer that will be prevailing prayer.
I Chronicles 5
1 Now the sons of Reuben the firstborn of Israel, (for he was the firstborn; but, forasmuch as he defiled his father’s bed, his birthright was given unto the sons of Joseph the son of Israel: and the genealogy is not to be reckoned after the birthright.
2 For Judah prevailed above his brethren, and of him came the chief ruler; but the birthright was Joseph’s:)
3 The sons, I say, of Reuben the firstborn of Israel were, Hanoch, and Pallu, Hezron, and Carmi.
4 The sons of Joel; Shemaiah his son, Gog his son, Shimei his son,
5 Micah his son, Reaia his son, Baal his son,
6 Beerah his son, whom Tilgath-pilneser king of Assyria carried away captive: he was prince of the Reubenites.
7 And his brethren by their families, when the genealogy of their generations was reckoned, were the chief, Jeiel, and Zechariah,
8 And Bela the son of Azaz, the son of Shema, the son of Joel, who dwelt in Aroer, even unto Nebo and Baal-meon:
9 And eastward he inhabited unto the entering in of the wilderness from the river Euphrates: because their cattle were multiplied in the land of Gilead.
10 And in the days of Saul they made war with the Hagarites, who fell by their hand: and they dwelt in their tents throughout all the east land of Gilead.
11 ¶ And the children of Gad dwelt over against them, in the land of Bashan unto Salchah:
12 Joel the chief, and Shapham the next, and Jaanai, and Shaphat in Bashan.
13 And their brethren of the house of their fathers were, Michael, and Meshullam, and Sheba, and Jorai, and Jachan, and Zia, and Heber, seven.
14 These are the children of Abihail the son of Huri, the son of Jaroah, the son of Gilead, the son of Michael, the son of Jeshishai, the son of Jahdo, the son of Buz;
15 Ahi the son of Abdiel, the son of Guni, chief of the house of their fathers.
16 And they dwelt in Gilead in Bashan, and in her towns, and in all the suburbs of Sharon, upon their borders.
17 All these were reckoned by genealogies in the days of Jotham king of Judah, and in the days of Jeroboam king of Israel.
18 ¶ The sons of Reuben, and the Gadites, and half the tribe of Manasseh, of valiant men, men able to bear buckler and sword, and to shoot with bow, and skilful in war, were four and forty thousand seven hundred and threescore, that went out to the war.
19 And they made war with the Hagarites, with Jetur, and Nephish, and Nodab.
20 And they were helped against them, and the Hagarites were delivered into their hand, and all that were with them: for they cried to God in the battle, and he was intreated of them; because they put their trust in him.
21 And they took away their cattle; of their camels fifty thousand, and of sheep two hundred and fifty thousand, and of asses two thousand, and of men an hundred thousand.
22 For there fell down many slain, because the war was of God. And they dwelt in their steads until the captivity.
23 ¶ And the children of the half tribe of Manasseh dwelt in the land: they increased from Bashan unto Baal-hermon and Senir, and unto mount Hermon.
24 And these were the heads of the house of their fathers, even Epher, and Ishi, and Eliel, and Azriel, and Jeremiah, and Hodaviah, and Jahdiel, mighty men of valour, famous men, and heads of the house of their fathers.
25 ¶ And they transgressed against the God of their fathers, and went a whoring after the gods of the people of the land, whom God destroyed before them.
26 And the God of Israel stirred up the spirit of Pul king of Assyria, and the spirit of Tilgath-pilneser king of Assyria, and he carried them away, even the Reubenites, and the Gadites, and the half tribe of Manasseh, and brought them unto Halah, and Habor, and Hara, and to the river Gozan, unto this day.
I Chronicles 3-8 – J. Vernon McGee
I Chronicles 5:20—They cried to God in the battle, and He was intreated of them.
Whether they cried to God before they went into the battle we are not told; but probably they did, because we read that the war was of God, and it is hardly likely that they would have prayed to Him in the midst of the fight, when the foemen’s blows fell like hail on their armor, if they had not prayed before they entered the bloody fray. Men often excuse themselves for neglecting their morning devotions by saying that they will surely look to God, as they may require His gracious help, in the midst of the day’s temptations and needs; but, as a matter of fact, when once they are plunged into its war they forget to look up. You must direct your prayer in the morning, and look up the early shadows lie long on the dewy grass, if you would keep looking off to Jesus, amid the din of the fight.
It is very lovely to contract and preserve this habit of looking upward, and crying to God in the battle. When our feet are slipping, when the foe seems about to overmaster, when heart and flesh fail-how refreshing and strengthening to fling one eager look or cry to heaven, and say, “I am thine, save me.” There can be no doubt as to the issue. God is always intreated of those who put their trust in Him. Sooner might a mother forget her sucking child than God be unmindful of one sigh, or tear, or upward glancing look from His own. Oh, child of God, put thou thy trust in God, and go through this tempestuous world as one who is confident of a Divine Ally. At any moment He will ride on the heavens to thy help. “Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need” (Hebrews 4:16) —Our Daily Homily
