'Heart' in the Bible

You have made my heart beat faster, my sister, my bride. You have made my heart beat faster with one glance of your eyes, with one strand of your necklace.

I was asleep, but my heart was awake. There's a sound! My beloved is knocking. "Open up for me, my sister, my darling, my dove, my perfect one. For my head is drenched with dew, my hair with the dampness of the night."

Set me like a seal over your heart, like a seal on your arm. For love is as strong as death, passion as intense as Sheol. The flames of love are flames of fire, a blaze that comes from the LORD.
