"During the greater part of this time of apostasy in Israel, Asa was ruling in the kingdom of Judah. For many years “Asa did that which was good and right in the eyes of the Lord his God: for he took away the altars of the strange gods, and the high places, and brake down the images, and cut down the groves: and commanded Judah to seek the Lord God of their fathers, and to do the law and the commandment. Also he took away out of all the cities of Judah the high places and the sun [margin] images: and the kingdom was quiet before him.” 2 Chronicles 14:2-5 . PK 110.1"
"And Asa did that which was good and right in the eyes of the Lord his God:"
EGW directly quotes 2 Chronicles 14:2.
"And Asa did that which was good and right in the eyes of the Lord his God: For he took away the altars of the strange gods, and the high places, and brake down the images, and cut down the groves: And commanded Judah to seek the Lord God of their fathers, and to do the law and the commandment. Also he took away out of all the cities of Judah the high places and the images: and the kingdom was quiet before him."
Ellen White directly references 2 Chronicles 14:2-5 in this passage.
"The faith of Asa was put to a severe test when “Zerah the Ethiopian with an host of a thousand thousand, and three hundred chariots,” invaded his kingdom. Verse 9 . In this crisis Asa did not put his trust in the “fenced cities in Judah” that he had built, with “walls, and towers, gates, and bars,” nor in the “mighty men of valor” in his carefully trained army. Verses 6-8 . The king's trust was in Jehovah of hosts, in whose name marvelous deliverances had been wrought in behalf of Israel of old. Setting his forces in battle array, he sought the help of God. PK 110.2"
"And there came out against them Zerah the Ethiopian with an host of a thousand thousand, and three hundred chariots; and came unto Mareshah."
EGW directly quotes 2 Chronicles 14:9.
"Some trust in chariots, and some in horses: but we will remember the name of the Lord our God."
Both passages contrast trusting in military might with trusting in God. Asa didn't trust in his army, and Psalm 20:7 states some trust in chariots, but the psalmist trusts in God.
"The opposing armies now stood face to face. It was a time of test and trial to those who served the Lord. Had every sin been confessed? Had the men of Judah full confidence in God's power to deliver? Such thoughts as these were in the minds of the leaders. From every human viewpoint the vast host from Egypt would sweep everything before it. But in time of peace Asa had not been giving himself to amusement and pleasure; he had been preparing for any emergency. He had an army trained for conflict; he had endeavored to lead his people to make their peace with God. And now, although his forces were fewer in number than the enemy, his faith in the One whom he had made his trust did not weaken. PK 110.3"
"And Asa cried unto the Lord his God, and said, Lord, it is nothing with thee to help, whether with many, or with them that have no power: help us, O Lord our God; for we rest on thee, and in thy name we go against this multitude. O Lord, thou art our God; let not man prevail against thee."
The EGW passage elaborates on the context and mindset of Asa before his prayer in 2 Chronicles 14:11, highlighting his preparation and faith. It amplifies the themes of trust in God and preparation for trials found in the biblical narrative.
