Before beginning to lay out his plans, he desired to determine the most favorable moment for his undertaking, which he did by casting lots.
First of all he wanted to decide on the day of the week. The scribe Shimshai began to cast lots. Sunday appeared inappropriate, being the day on which God created heaven and earth, whose continuance depends on Israel's existence. Were it not for God's covenant with Israel, there would be neither day nor night, neither heaven nor earth. Monday showed itself equally unpropitious for Haman's devices, for it was the day on which God effected the separation between the celestial and the terrestrial waters, symbolic of the separation between Israel and the heathen. Tuesday, the day on which the vegetable world was created, refused to give its aid in bringing about the ruin of Israel, who worships God with branches of palm trees. Wednesday, too, protested against the annihilation of Israel, saying: "On me the celestial luminaries were created, and like unto them Israel is appointed to illumine the whole world. First destroy me, and then Thou mayest destroy Israel." Thursday said: "O Lord, on me the birds were created, which are used for sin offerings. When Israel shall be no more, who will bring offerings? First destroy me, and then Thou mayest destroy Israel." Friday was unfavorable to Haman's lots, because it was the day of the creation of man, and the Lord God said to Israel, "Ye are men." Least of all was the Sabbath day inclined to make itself subservient to Haman's wicked plans. It said: "The Sabbath is a sign between Israel and God. First destroy me, and then Thou mayest destroy Israel!"
