To follow someone's teaching with avidity / to sit amid the dust of their feet / to study under
In the question: He sought his nearness and was humbled before him. Or: He was his disciple and taught from him in adoration (according to the interpretation of R. Obadiah from Bartenura to Mishnah, in the old days the teacher would sit on a throne and his disciples would sit on the floor at his feet, and therefore there would be dust in his proximity).
("Yosei ben Yoezer, a man of Tzareda, and Yozei ben Yochanan, a man of Jerusalem, received from them, Yozei ben Yoezer, saying, "Let your house be a house of prayer for the wise, and let me be dusted with the dust of their feet, and let me be a drinker of their words in my thirst" - Avot 1:4, and so: "...that is how they behaved, that the one who was often seated on the throne and the disciples sat at his feet. "On the back of the sky" - Parush Bretonora there, and also: "And a large dog jumped on him... But the dog did him no harm, only dusted himself with the dust of his feet and licked his clothes" - Agnon/ And there was a curve to the right, 4, 96, and also: "And from here and there, dusting himself with the dust of his feet and like a trampled hare" - H. Hazaz/ Dorot Harashonim, 98, And so: "The great Rabbi, the Hasidic Rabbi Isaiah Horvitz, the Baal of the Holy Shelah... taught Torah to all the children of the Diaspora. His house was open to the spirit, and students from the four corners of the earth, the poor and the rich, came to dust themselves in the dust of his feet. His house was a house of honor even for the wise" - Mordechai ben Yehezkel / Sefer Hamaashyot Quadrilateral, face reception, 295)
