From where.

The Pharisees therefore said unto him, Thou bearest record of thyself; thy record is not true. Jesus answered and said unto them, Though I bear record of myself, yet my record is true: for I know WHENCE I came, and whither I go; but ye cannot tell WHENCE I come, and whither I go. ( John 8:13-14 )
