Yeshayah 51:9-11

Awake, awake, clothe thyself with oz, O zero'a HASHEM; awake, as in the yemei kedem, in the dorot olamim. Art thou not it that hath cut Rachav to pieces, and pierced Tannin. Art thou not the One Who hath dried the yam, the waters of the tehom rabbah; that hath made the depths of the yam a derech for the ge'ulim (redeemed ones) to cross over? Therefore the Redeemed of HASHEM shall return, and come with singing unto Tziyon; and simchat olam shall be upon their rosh; they shall obtain sasson and simchah; and sorrow and mourning shall flee away.
