«And the nesekh (libation offering) thereof shall be the fourth-hin for the one keves: baKodesh (i.e., the Mizbe'ach) shalt thou cause the nesekh shekhar to be poured out unto Hashem.» Bamidbar 28:7 OJB
«And thou shalt spend that kesef for whatsoever thy nefesh desireth after, for cattle, or for sheep, or for yayin, or for shekhar (fermented drink), or for whatsoever thy nefesh desireth; and thou shalt eat there before Hashem Eloheicha, and thou shalt rejoice, thou, and thine household,» Devarim 14:26 OJB
«(5) Ye have not eaten lechem, neither have ye drunk yayin or shekhar; that ye might have da'as that Ani Hashem Eloheicha.» Devarim 29:6 OJB
