Holiness in space, in nature, was known in other religions. New in the teaching of Judaism was that the idea of holiness was gradually shifted from space to time, from the realm of nature to the realm of history, from things to events. The physical world became divested of any inherent sanctity. There were no naturally sacred plants or animals any more. To be sacred, a thing had to be consecrated by a conscious act of man. The quality of holiness is not in the grain of matter. It is a preciousness bestowed upon things by an act of consecration and persisting in relation to God.
Abraham Joshua Heschel, The Sabbath: Its Meaning for Modern Man
Baruch Ata Adonai Elo-hei-nu me-lech ha-olam a-sher ke-d-sha-nu b- mitz-vo-tav, v-tzi-va-nu al s-fi-rat ha-omer.
Praised be you Adonai our God who rules the Universe instilling within us the holiness of mitzvot by commanding us to count the Omer.
Today is the forty-fifth day of the Omer.
