What would the wise King Solomon have to say about how to select an adviser?  I surmised in a novel excerpt, based on his proverbs, what he may have advised the Queen of Sheba to answer her question.
Excerpt
“Solomon, when you travel to your providence’s, what information do you seek to ascertain the truth of whether or not your appointees are capable and loyal leaders?” 
“Bilqis, one of the most important duties of a leader is to appoint the best and most capable leaders to maintain order and progress in their kingdom. I strongly believe in delegating responsibility to those I appoint to maintain order for the day-to-day tasks. I also believe a leader should travel often and check on their progress and to maintain strong personal relationships to promote trade and unity.”
“An ideal governor is an upright truthful man. A community will thrive on the candor of their governor. A king loves the candid man with integrity in his circle of advisors.” A king approves truthful speech, and loves the words of upright men. (Proverb 16:13)
“A ruler is deserving of the kind of leaders he appoints. If a ruler wants his officials to be a stickler for truth and goodness, he must himself be a stickler to attract men of caliber into his service. Men of integrity will not tolerate and serve a king that lacks rigor and probity. A king must investigate to find the truth of every affair. If the king is slack and irresponsible to seek truth, the lies of the wicked will prevail and reflect upon the king. Wicked men poison the life of the community for their own ends will seize the opportunity to serve a master of their own kind.” A ruler who gives credence to a lie, all who serve him are wicked men. (Proverb 29:12)
