The witch's excitement grew when she perceived a number of spirits arise by the side of Samuel. The dead prophet, when he was summoned back to earth, thought that the judgement day had arrived. He requested Moses to accompany him and testify to his always having executed the ordinances of the Torah as Moses had established them. With these two great leaders a number of the pious arose, all believing that the day of judgment was at hand. Samuel was apparelled in the "upper garment" his mother had made for him when she surrendered him to the sanctuary. This he had worn throughout his life, and in it he was buried. At the resurrection all the dead wear their grave clothes, and so it came about that Samuel stood before Saul in his well-known "upper garment."
