Then I Looked, and there was the Lamb, standing on Mount Zion! And with him were one hundred fortyfour thousand who had his name and his Father’s name written on their foreheads (Rev. 14:1)

Saint John gazes up at the Lamb of God on Mount Zion. The Lamb is worshipped by two groups of men, who represent the 144,000 redeemed.
