In John 8:6, We don't really know what Jesus wrote on the ground with his finger when they brought him the woman taken in the act of adultery, but we do know that...
God gave unto Moses....two tables of testimony, tables of stone, written with the finger of God. Exodus 31:18
and we know that Jesus said....
A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. John 13:34
