ISA 50:4

4 Adonoi Hashem hath given Me the leshon limmudim[(learned tongue of disciples)], that I should know how to speak a devar [(word, i.e., word of consolation)] in season to him that is weary; He wakeneth baboker baboker [(morning by morning)], He wakeneth Mine ozen [(ear)] to hear as the limmudim [(disciples, those being taught)].
