It is our duty to praise the Master of all, to ascribe greatness to the Author of creation, who has not made us like the nations of the lands nor placed us like the families of the earth; who has not made our portion like theirs, nor our destiny like all their multitudes. But we bow in worship and thank the Supreme King of kings, the Holy One, Blessed be He.”
“Reign over us son and forever. May the kingdom of David’s greater son be established forever. For the Kingdom is Yours, and all eternity You will reign in glory, as it is written in Your Torah: The LORD shall be King forever, and The LORD shall be King over all the earth; on that day, the LORD shall be One and His name shall be One.
The Aleynu states it is our duty to praise God, meaning “it is upon us or it is our obligation or duty to praise God.” What a glorious obligation to praise the God of Israel who has given us both physical and spiritual Life! A folkloric tradition attributes this prayer to the biblical Joshua at the time of his conquest of Jericho. This might have been inspired by the fact that the first letters of the first four verses spell, in reverse, Hoshea, which was the childhood name of Joshua (Numbers 13:16). Another attribution is to the Men of the Great Assembly, during the period of the Second Temple.
