'Seclusion' in the Bible

So Jonathan told David, "My father Saul is trying to kill you. So be careful tomorrow morning. Find a hiding place and stay in seclusion.

(The Bridegroom)“O my dove, [here] in the clefts in the rock,In the sheltered and secret place of the steep pathway,Let me see your face,Let me hear your voice;For your voice is sweet,And your face is lovely.”
