'Within' in the Bible

Then they approached {and spoke with the king} concerning the edict of the king, "{Did you not sign an edict} that any person who would seek [anything] from any God or human within thirty days except from you, O king, would be thrown into {the lion pit}?" The king answered and said, "The matter [as you have just stated] is certain according to [the] law of [the] Medes and Persians which cannot be revoked."

"{As for me, Daniel}, my spirit was troubled {within me}, and the visions of my head terrified me.
