Num Numbers, chapter Book of Numbers, chapter 10
And in the day of yöur gladness, and in yöur appointed times, and in the beginnings of yöur months, yöu have also blown with the trumpets over yöur burnt-offerings, and over the sacrifices of yöur peace-offerings, and they have been for a memorial to yöu before yöur God; I [am] yöur God YHWH.” Num 28:14; 2Ki 11:14; 2Ch 7:6
