'Head' in the Bible

“Let his left hand be under my headAnd his right hand embrace me.”

“I was asleep but my heart was awake.A voice! My beloved was knocking:‘Open to me, my sister, my darling,My dove, my perfect one!For my head is drenched with dew,My locks with the damp of the night.’

“His head is like gold, pure gold;His locks are like clusters of datesAnd black as a raven.

“Your head crowns you like Carmel,And the flowing locks of your head are like purple threads;The king is captivated by your tresses.

“Let his left hand be under my headAnd his right hand embrace me.”
