The Seder leader continues, “Therefore, we are obligated to thank, praise, laud, glorify, adore, exalt, magnify and honor the One Who performed all these miracles for us. He took us out from slavery to freedom, from sorrow to joy, from intense darkness to great light. Let us recite praises before Him: Hallelujah!" The first part of Hallel is recited at this point, “Hallelujah! Servants of God, give praise” through “He turns the flint into a stream of water.” He concludes with the bracha that God redeemed us and our ancestors from Egypt and has enabled us to reach this night in order to eat matzah and maror. Nowadays, one adds, “Similarly, Hashem, our God and the God of our fathers, enable us to reach other festivals and holidays that will come to us in peace, rejoicing in the rebuilding of Your city and celebrating in Your service. Then, we will eat from the sacrifices and Passover offerings whose blood will be sprinkled on the wall of Your altar to be graciously accepted. Then, we will offer thanks to You with a new song for our redemption and for the deliverance of our souls. Blessed are You, God, Who redeemed Israel.” The leader recites the bracha of hagafen and everyone drinks the second cup of wine.
