in John 19:28: “Later, knowing that everything had now been finished, and so that Scripture would be fulfilled, Jesus said, ‘I am thirsty.’”
John 19. 29 "Now there was set a vessel full of vinegar: and they filled a spunge with vinegar, and put it upon hyssop, and put it to his mouth" (Vingegar was Wine and with Water, Hyssop was used to add the Blood to the doors of the Israeites at the Exodus see
12.22 “And ye shall take a bunch of hyssop, and dip it in the blood that is in the bason, and strike the lintel and the two side posts with the blood that is in the bason; and none of you shall go out at the door of his house until the morning.”
John 19:30-40 "But one of the soldiers pierced His side with a spear, and immediately blood and water came (flowed) out. And he who saw it (the eyewitness) gives this evidence, and his testimony is true; and he knows that he tells the truth, that you may believe also" https://www.bible.com/bible/8/JHN.19.30-40.AMPC
On the 18th of Tishrei, the 3rd day of chol hamoed – the intermediary days of the Festival of Sukkot (Sunday, Oct. 12 2014) – history was made in Jerusalem. For the first time since the destruction of the Second Temple, a reenactment of the famed Festival of the Water Libation (Simchat Beit HaShoeva) was held, under the direction of the Temple Institute and in cooperation with the Association of Temple Organizations. Cohanim (men of priestly descent) dressed in priestly garments, accompanied by a crowd estimated at many hundreds, descended to the ancient Shiloach spring in the City of David, and drew water in a special Temple vessel. The ceremony was marked by dancing and singing, and the sounding of blasts from the shofar and silver trumpets. By the time the procession reached the old city of Jerusalem, the ranks of participants had swelled to well over one thousand.
The sages of Israel state that “whoever has not seen the Festival of the Water Libation has never seen true joy” (Tractate Sukkot 51:a). This celebration, which took place EVERY NIGHT during the Sukkot festival in the Holy Temple, was the height of the holiday joy of Sukkot, and the purest fulfillment of the Biblical commandment, “And you shall rejoice on your festival, and you shall be only joyous” (Deut. 16). The drawing of the water from the Shiloach spring is associated with the verse (Is. 12:3) “You shall draw water with joy from the springs of salvation,” and is a unique tradition that Moses received at the Sinai Revelation. At dawn, the water was taken up to the Temple Mount and poured into a vessel on the corner of the altar. This ceremony is also associated with the resting of the spirit of prophecy upon the people of Israel.
