At Lauds (morning office), we pray the Benedictus (Luke 1:68-79).
Rather than flip to the Benedictus, this divider tab keeps the text of the Benedictus in the group of dividers I move in a group day by day (and during the day as well).
This set of dividers was made for an oblate friend who likes the Jerusalem Bible. I do not have the Jerusalem Bible and could not find one online. I did find the New Jerusalem Bible online and so I used the NJB for this divider's text.
On the back of this divider is the Magnificat which is prayed at Vespers (evening prayer).
