Everyone knows the hymn, “O Come, O Come, Emmanuel.” Not everyone knows that it has its roots in an older tradition called the ‘O’ Antiphons, which were used at Vespers (the late afternoon/early evening prayer office) from December 17 until December 23. In the Lutheran Service Book, they are printed on the opposite page from the hymn. Here’s a good explanation of them.
And from the hymn: “O come, Thou Wisdom from on high,/Who ord’rest all things mightily;/To us the path of knowledge show,/And teach us in her ways to go” (LSB 357:2).
Rejoice! Emmanuel shall come to thee, O Israel!
