Chasidut zu Bereschit 24:2

And you will understand through this what our Sages taught about the faithful servant of Abraham, our father, that he was the very first of those connected to us, and the blessed Holy One raised him higher than the constellations (see Gen. 15:5 with Rashi). The verse “his servant, the elder of his household” (Gen. 24:2), they explain with, “he one in charge of my household is Dammesek Eliezer!” (Gen. 15:2), meaning that he draws [doleh] and gives drink [mashke] to others from his master’s Torah (Yoma 28b).
