Gilgal is a place named in the Bible as being on the eastern border of Jericho. It is also the scene of one of the bloodiest murders in the Old Testament. After the Amalekites ambush the Israelites on their way out of Egypt, God issues an injunction to wipe out the whole of their race. The king, Agag, is initially spared by the mercy of King Saul, an act which the prophet Samuel sees as a blasphemous refusal of God’s orders. To atone for this failure, he takes matters into his own hands with brutal effect.
