[212] Rehoboam now called his father's friends, and advised with them what sort of answer he ought to give to the multitude; upon which they gave him the advice which became friends, and those that knew the temper of such a multitude. They advised him to speak in a way more popular than suited the grandeur of a king, because he would thereby oblige them to submit to him with goodwill, it being most agreeable to subjects that their kings should be almost upon the level with them. But Rehoboam rejected this so good, and in general so profitable, advice, (it was such, at least, at that time when he was to be made king,) God himself, I suppose, causing what was most advantageous to be condemned by him. So he called for the young men who were brought up with him, and told them what advice the elders had given him, and bade them speak what they thought he ought to do. They advised him to give the following answer to the people (for neither their youth nor God himself suffered them to discern what was best): That his little finger should be thicker than his father's loins; and if they had met with hard usage from his father, they should experience much rougher treatment from him; and if his father had chastised them with whips, they must expect that he would do it with scorpions. ¹ The king was pleased with this advice, and thought it agreeable to the dignity of his government to give them such an answer. Accordingly, when the multitude was come together to hear his answer on the third day, all the people were in great expectation, and very intent to hear what the king would say to them, and supposed they should hear somewhat of a kind nature; but he passed by his friends, and answered as the young men had given him counsel. Now this was done according to the will of God, that what Ahijah had foretold might come to pass.
