"set me as a seal upon your heart"

We announced our engagement in church yesterday morning, then talked about the wedding in the afternoon. Heather liked the scriptures I had chosen (here and here). But she wanted to add this to the Song of Songs reading:

Set me as a seal upon your heart, as a seal upon your arm; for love is strong as death, passion fierce as the grave. Its flashes are flashes of fire, a raging flame. Many waters cannot quench love, neither can floods drown it. (Song 8.6-7)

I really like that. She also suggested that I read the first Song passage during the wedding, and she read this one. We may read Psalm 34 together, too:

O magnify the LORD with me, and let us exalt his name together!
