A Bible Study by Jack Kelley
And Jonathan made a covenant with David because he loved him as himself. Jonathan took off the robe he was wearing and gave it to David, along with his tunic, and even his sword, his bow and his belt. (1 Samuel 18:3-4)
The making of a covenant was serious business. It was the strongest bond known to men, and had both business and personal applications that extended even to the descendants of the two parties involved. A covenant was typically solemnized by great ceremony and ritual, some of which is mentioned in the passage above. All in all it went like this.
First, several animals were cut in half and arranged along a path. Their purpose was to symbolize the penalty for breaking the covenant. The two men entering into a covenant relationship walked between and around the animal parts in a figure eight. (An eight on its side is the symbol for infinity.) This was to show that they understood and accepted the penalty and that the agreement committed them forever. (When God entered into His covenant with Abraham, promising him an heir and giving him the Promised Land, He was the only one who walked between the animals. This meant that only He was bound to the terms. There was nothing Abraham had to do. In fact, God put him to sleep so he couldn’t participate. The land was given to Abraham and his descendants unconditionally and in perpetuity (Gen.15:9-21).
