It is said: "They shall praise him in his eyes," hence the Sages said: "A man's mind shall always be mixed with the people" – Articles 17a, and also: "And if his speech was at peace with the people, and his mind mingled with them... After all, it sanctifies God" – Maimonides / Sefer Ha-Mada, Hilkhot Yesodei Torah, chapter five, 11, 87, and also: "And the more they revered him for his great power and his strong hand, the more they loved him for his opinion that mingled with them, for their tongue that was used according to him for all its subtleties and delusions" – Bialik / Aryeh Baal Goff, 6:30)
