In the next step, each man would take something like wood ash and rub it into the cut in his hand. This would eventually heal over and become a dark scar.
When he needed to show someone he was in a Blood Covenant relationship he would just hold up his hand and show his scar. When people saw the scar they realized that they were not only dealing with this man but his Covenant Partner also.
~ TODAY WE HAVE A BETTER COVENANT, AS PROPHESIED BY JEREMIAH 31:31 ~
IN THE NEW COVENANT: We have the seal of the Holy Spirit (Ephesians 1:13; 4:30) as evidence that we have entered into the New Covenant with God through his Son, Jesus.
