Charles H. Spurgeon on Psalms 105:22

And teach his senators wisdom. That in that wisdom wherein he had been instructed of God he might also instruct the princes, and teach prudence to those who were much his seniors. Herein some sparks of divine wisdom shine, that he should order even the princes and old men to learn wisdom from one who was a slave and a foreigner, although the Egyptians are always want to boast that Egypt is the native place of wisdom. Yansenius.
