"Chapter 15—Jehoshaphat Until called to the throne at the age of thirty-five, Jehoshaphat had before him the example of good King Asa, who in nearly every crisis had done “that which was right in the eyes of the Lord.” 1 Kings 15:11 . During a prosperous reign of twenty-five years, Jehoshaphat sought to walk “in all the ways of Asa his father; he turned not aside.” PK 190"
"And Asa did that which was right in the eyes of the Lord, as did David his father."
EGW directly quotes 1 Kings 15:11 in reference to King Asa and his righteousness in the eyes of the Lord.
"And he walked in all the ways of Asa his father; he turned not aside from it, doing that which was right in the eyes of the Lord: nevertheless the high places were not taken away; for the people offered and burnt incense yet in the high places."
The EGW passage directly quotes 1 Kings 15:11 and 1 Kings 22:43, making this an explicit allusion rather than a thematic parallel. The confidence is increased due to the direct quotation.
"In his efforts to rule wisely, Jehoshaphat endeavored to persuade his subjects to take a firm stand against idolatrous practices. Many of the people in his realm “offered and burnt incense yet in the high places.” 1 Kings 22:43 . The king did not at once destroy these shrines; but from the beginning he tried to safeguard Judah from the sins characterizing the northern kingdom under the rule of Ahab, of whom he was a contemporary for many years. Jehoshaphat himself was loyal to God. He “sought not unto Baalim; but sought to the Lord God of his father, and walked in His commandments, and not after the doings of Israel.” Because of his integrity, the Lord was with him, and “stablished the kingdom in his hand.” 2 Chronicles 17:3-5 . PK 190.2"

The EGW passage directly quotes 2 Chronicles 17:3-5. This is an explicit allusion.
"And the Lord was with Jehoshaphat, because he walked in the first ways of his father David, and sought not unto Baalim; But sought to the Lord God of his father, and walked in his commandments, and not after the doings of Israel. Therefore the Lord stablished the kingdom in his hand; and all Judah brought to Jehoshaphat presents; and he had riches and honour in abundance."
