'Hand' in the Bible

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

“My beloved extended his hand through the opening [of the door],And my feelings were aroused for him.

(The Bridegroom)“Why should you gaze at the Shulammite,As at the dance of the two armies?“How beautiful are your feet in sandals,O prince’s daughter!The curves of your hips are like jewels,The work of the hands of an artist.

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