Psalm 139:6 Meaning

4For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether.

5Thou hast beset me behind and before, and laid thine hand upon me.

6Such knowledge is too wonderful for me; it is high, I cannot attain unto it.

7Whither shall I go from thy spirit? or whither shall I flee from thy presence?

8If I ascend up into heaven, thou art there: if I make my bed in hell, behold, thou art there.
